Quick Reference Trouble Shooting GuideOverview OVERVIEW This cocument is for Media Vision's Pro Audio Spectrum 16C sound baord, part number 650-0022-01, with installation diskette titled: PAS 16 Install Disk Version 1.45 P/N: 557-0067-01 with windows drivers disk version 1.45 Other versions of the installation diskette may vary slightly, but are functionally equivalent. This guide provides basic troubleshooting procedures, general test procedures and lists functions and features that are typically asked about, along with an alphabetical listing of problems, symptoms and the normal solutions. The descriptions are stated the way customers most commonly refer to them. The solution steps are listed in the order of which they most frequently resolve the problem. In this document, everything in italics is text you type in from the keyboard. Control keys (Control, Alt, Delete, Enter, etc) are specified as , etc. PAS 16 and Pro Audio Spectrum 16 are used interchangeably. Please refer to you DOS manuals for information on commands you are not familiar with and for instructions on using the DOS EDIT program. The DOS manuals are also the best reference for resolving issues concerning errors about 'Not Enough Memory' when trying to run applications. If you DON'T KNOW WHERE TO START, go to the "TESTING" sections and perform the tests in the sequence that they are listed. If a problem occurs, look up that problem or symptom, follow the steps and re test. BEFORE CALLING TECHNICAL SUPPORT Perform all of the steps in the Basic Troubleshooting section. Have the following information available: Make a list of all peripheral devices in your system and the DMA or IRQ used by each if any. Some common examples would be a scanner, tape backup, SCSI controller, fax/modem or bus mouse. Make sure there are no conflicts with the DMA's or IRQ's that were selected for the PAS 16. To determine the DMA and the IRQ setting for the PAS 16: Edit your config.sys file. Find the line that contains the name "MVSOUND.SYS". In this line, "D:x" gives the value of the chosen DMA; "Q:x" gives the value of the IRQ setting for the PAS 16 portion of the card. The DMA and IRQ for the Sound blaster portion of the card are set at the end of this statement : "S:1,,, M:0". (Refer to the Utilities Guide for more details of these parameters.) Check that you don't have another sound device or another joystick port in the system. Follow the Standard troubleshooting steps below. If you need to call technical support the information we will request is computer type, name brand and model, is it a 286, 386 or 486, CPU speed and is the BUS speed at 8mhz. If you have any other cards in the system please let us know. BASIC TROUBLESHOOTING STEPS A. If you do not hear any sound, but do not get any error messages, recheck that the speakers are plugged into the correct jack, replace the speakers with headphones to see if speakers are defective and / or connect the speakers to another audio device (such as a cassette player) to test the speakers. B. If you previously had any sound board in you computer, make sure that you remove ALL references to the previous sound board from CONFIG.SYS, AUTOEXEC.BAT, SYSTEM.INI, WIN.INI. You may need to contact the manufacturer of the previous sound board for assistance. C. If your computer automatically starts Windows 3.1 on boot up: 1. Edit your 'AUTOEXEC.BAT' file. 2. Locate the line that starts Windows. It should be at the bottom of the file and normally will say "WIN" or "WIN/3" or "C:\WINDOWS\WIN". Insert REM at the beginning of the line to temporarily stop Windows from loading. You may remove the 'rem' after your PAS 16 is successfully installed if you wish to automatically start Windows on bootup. 3. Re-boot your computer and perform the DOS tests. D. Checking for errors during boot up: 1. If you are running MS-DOS 6.2 or above: a. While your system is booting, watch for the message "Starting MS- DOS" and press the function key immediately. b. You will get the message "DOS will prompt you to confirm each setting." And DOS will display each line in the CONFIG.SYS and AUTOEXEC.BAT files. c. Respond to each prompt by pressing Y for yes. If you receive any error messages, refer to the alphabetical listing below. If the error is not listed, refer to your DOS manual, or the manual for your other hardware. The error may have existed before installing your Pro Audio 16. 2. If you are running MS-DOS 6.0: a. Follow the procedure above, EXCEPT MS-DOS 6.0 will not prompt you for the lines in the AUTOEXEC.BAT file. b. Edit the AUTOEXEC.BAT and insert PAUSE (see your DOS manual) every 2nd or 3rd line. c. Re-boot your computer and as the AUTOEXEC.BAT file is executing, it will stop at each PAUSE statement with a message "Pause, press any key to continue." Pressing a key will continue to the next PAUSE statement. 3. For DOS 5.0: DOS 5 will not allow you to step through the config.sys or autoexec.BAT files. You must use the "pause" statements described above, making sure you have a pause as your first line in autoexec.bat in order to see most of config.sys. E. Temporarily use the generic CONFIG.SYS and AUTOEXEC.BAT files below. GENERIC CONFIG.SYS: DEVICE = C:\DOS\HIMEM.SYS FILES = 30 BUFFERS = 10 DEVICE=C:\PROAUDIO\MVSOUND.SYS D:3 Q:7 J:0 T:1 /W:0 GENERIC AUTOEXEC.BAT: SET BLASTER=A220 D1 I5 T3 PATH=C:\;C:\DOS;C:\WINDOWS;C:\PROAUDIO PROMPT $P$G F. Temporarily reduce the computer's CPU speed. Usually this can be accomplished by turning off the TURBO mode or disabling the internal/external memory cache by going into the computer's CMOS setup. G. Temporarily reduce the computer's bus (I/O CLK) speed to 8MHz. All Media Vision products are designed for the IBM AT specification which uses this bus speed. Please note that this is not the same as the CPU speed. Once everything works fine at 8MHz bus speed, you can experiment at a higher bus speed. Refer to your computer's documentation or the manufacturer for assistance. H. Try the sound board in another 16-bit slot. I. Temporarily remove other peripheral boards from the computer, such as scanner board, tape backup and modem. J. Try the Media Vision product in another computer. K. Locate the symptom/problem in the below listing and follow the steps listed, re-testing after each step. TEST PROCEDURE FOR PAS 16 Refer to the alphabetical listing for symptoms or error messages encountered during tests. A. DOS TEST 1. Verify DMA and IRQ settings: a. For the PAS 16 side of the board: Use the DOS type command to display the CONFIG.SYS file. Locate the line with MVSOUND.SYS. The D:x and Q:x parameters show you the DMA and IRQ that the sound driver is currently using. 2. Test Pro Audio 16 .WAV Files: a. From DOS (make sure you have exited windows, not just the "DOS Prompt" icon) change directories to Proaudio by typing: CD C:\PROAUDIO b. To test the .wav files, type: PLAYFILE CHORD.WAV You should hear a musical chord playing for 1 to 2 seconds. If the system locks up, it is usually a DMA conflict. If the sound is LOOPING, it is normally an IRQ conflict. See DMA in the alphabetical listing. 2. Sound Blaster Emulation: a. Install a DOS game that utilizes Sound Blaster, making sure you select the Port Address and IRQ the same as you selected for Sound Blaster Emulation during your Pro Audio 16 setup. Preferably the game will allow a selection of Sound Blaster for digital sound and Adlib for music. This will test both sections at the same time. B. WINDOWS TESTS 1. Open the Pocket Mixer in the Multi Media Tools group and adjust all volume controls (except the microphone) to about 75%, and set them to play mode. (Leave the mic below 50%.) See Pro Audio 16 Utilities Guide. 2. Open the Media Player in the Windows Accessories Group 3. Testing Wave: On the Media Player, click on "DEVICE." Then click on "SOUND". The open screen should show some sample .WAV files, CHIMES.WAV, CHORD.WAV, DING.WAV and TADA.WAV. Click on TADA.WAV and click OK. The file will load and the Media Player, the title bar should say "Media Player - tada.wav (stopped)." Click on the PLAY button (the right pointing arrow in the lower left corner). You should get a trumpet fanfare "TADAAAAA". 4. Testing Midi: On the Media Player, click on "DEVICE." Then click on "MIDI SEQUENCER." The "open" box should show one file on the left "CANYON.MID". Click on canyon.mid and click "OK". After the file loads, the Media Player title bar should say "Media Player - CANYON.MID (stopped)." Click the play button (the right pointing arrow in the lower left corner) and you should hear the song playing. C. CD-Rom Drive Test 1. From DOS: a. Log on to the CD-Rom drive. Type: D: (or the letter of your CD-Rom Drive) b. Insert a data cd (as opposed to a music cd) and type: DIR to read the directory. c. Copy a file from the CD-Rom Drive (any file) to your C: drive COPY D:\FILE.EXT C:\ d. Then compare the two files to insure the data was read and written correctly. FC D:\FILE.EXT C:\FILE.EXT Note: for DOS 5.0 users, the compare command is COMP e. If you should receive the message "FC: no differences encountered," the CD-Rom read and transferred data correctly f. Insert a music cd. Run the MUSICBOX.EXE from the ProAudio directory and play the cd. 2. From Windows a. Open the File Manager. Across the top of File Manager, you will see a row of drive icons. Check to see if the CD-ROM drive icon is displayed. The CD-Rom icon shows a cd half way inserted. (It looks like a tongue hanging out.) b. Insert a data cd in the CD-Rom and, on the file manager, click on the CD-Rom Drive icon. You should see the CD's directory. c. Copy a file to the hard drive. c. Insert a music cd in the CD-Rom d. Open the Pocket CD in the Multi Media Tools group and press the play button. e. The music should play. Adjust the mixer volume control as necessary. ALPHABETICAL LISTING OF SYMPTOMS / ERRORS / FUNCTIONS This listing is in alphabetical, by the terminology that is most frequently used by customers. Error messages are listed by the word "ERROR" first then the first significant word in the actual error message (exclude "a", "the").For problems and symptoms, the solution steps are listed in the order that they most often solve the problem or cure the symptom. CD-Audio Internal Connector, J5 is a 5-pin header connector, 0.100" space header, pin 1=ground, 2=right in, 3=ground, 4=left in, 5=ground. Compatibility With Other Hardware and Software A. Adaptec 1542B SCSI Hard Disk Controller: On some systems with the 1542 controller you will hear periodic clicking sound or static noise whenever the hard disk's light goes on (while drive is being accessed). Solution: Lower the bus on-time and increase the bus off-time by the same amount so that the on time is smaller than the off-time, or experiment to find the best ratio. The installation for this card adds the following statements to CONFIG.SYS: DEVICE=C:\ASPI4DOS.SYS /N11 /F5 DEVICE=C:\ASPIDISK.SYS Where N11 is 11/16ms and F5 is 5/16ms (default settings). The problem may be resolved by changing the parameters to N5 and F11. Configuring / Re-Configuring Your PAS 16 A. The preferred method of changing DMA/IRQ combinations is to re-run the installation program from the Pro Audio16 directory. 1. From DOS: (Make sure you have completely exited windows, not just a DOS Prompt) Type: CD C:\PROAUDIO 3. Now run the installation, type: INSTALL 4. Select "SET UP HARDWARE ONLY" and press 5. Answer the prompts about Windows on your system. 6. The INSTALL program will then display all of the settings for the sound board. 7. Use your cursor arrows to highlight the DMA or IRQ setting and press enter. A list of possible settings will be displayed (Not necessarily ones that are usable on your system). Select a setting and press . Highlight "accept the above settings" and press enter. You should hear a musical chord play. Follow the instructions on screen for problems. 11. After selecting your settings move to the bottom of the screen and select "ACCEPT THE CONFIGURATION" and press . Your system will update and it will prompt you to press F3 and reboot your system. DMA: Direct Memory Access: a "Channel" used by the system for efficient transfer of data to and from memory. A. Valid DMA channels are 0,1,2,3 (8 bit DMAs) and 4,5,6 & 7 (16 bit DMAs) B. DMA 4 & 6 are typically not available. C. Preferred DMA for Pro Audio (16 bit) is 5, 7 or 3. D. Required DMA for the Sound Blaster side of board is DMA 1. It can be set for other DMAs but the sound blaster compatible hardware will not be recognized by any software. E. Symptoms of DMA conflicts 1. Digital audio severely distorted 2. No audio 3. System reboots 4. System 'hangs' or 'locks up' 5. "MEMORY PARITY ERROR" 6. Installation program locks up while "Analyzing the System" F. Determining what DMAs are available 1. Check documentation for your system / motherboard 2. Check documentation for each interface / controller board installed in your system. 3. It may be necessary (and sometimes quicker) to use the installation routine and find available DMAs through trial and error. G. See Configuring / Re configuring you system. ERROR: "Can't find version 2.xx of VDMAD.386" WHY: Some program install has over written the VDMAD driver and changed it's name it the SYSTEM.INI file. A. Edit the SYSTEM.INI file. Scan down to the [386.enh] section and look for a line similar to the following: device=vdmadx.386 The line may say vdmad.386 or some other variation but it will always start with the device=vdma... Change the line to state only: device=*vdmad This will correct the error and whatever program inadvertently made the change will still work. ERROR: "CDR 101: Drive not ready" WHY: This is a standard DOS error message indicating that a readable disk was not found when the drive was accessed. This is similar to trying to read from your floppy drive when you forgot to insert your floppy disk. A. Make sure that you are not trying to read a CD-Audio disk. Music CDs don't contain data and are not "readable." Insert a program or data CD and try again. B. The CD you are trying to read may be defective. Try a different CD. If other CDs work, replace the CD. C. Check for errors during boot up. See "Basic Troubleshooting Steps" D. Check the SCSI cable to insure it is properly connected. Unplug and reinsert the cable on both the sound board and the CD-Rom. Re-test. E. Change to a generic CONFIG.SYS and AUTOEXEC.BAT files (see GENERIC CONFIG.SYS and GENERIC AUTOEXEC.BAT and re-test. ERROR: "CDR 103: CD-ROM not High Sierra or ISO-9660 format reading drive" WHY: The CD you are trying to read was not written in a standard format. A. Make sure that you are not trying to read a CD-Audio disk. B. Another driver / program is causing a conflict. Reduce to the generic CONFIG.SYS and AUTOEXEC.BAT and try again. ERROR: "Device driver not found: MVCD001. No valid CD-ROM selected" WHY: A DOS error message indicating that MSCDEX.EXE did not find the logical name "MVCD001". This 'name' should have been initialized by the CD-Rom driver (TSLCDR.SYS) in the CONFIG.SYS file. A. TSLCDR.SYS failed to load while the CONFIG.SYS was executing. See "Basic Troubleshooting Steps" for test and troubleshooting B. Some computers don't like having numbers (001) in this name and others are expecting a specific name for the CD-Rom device. Both the TSLCDR.SYS in CONFIG.SYS and MSCDEX.EXE in AUTOEXEC.BAT have a parameter "/D:MVCD001". Edit both of these files and change the parameter to read "/D:TSLCD". The parameter in both lines MUST be identical. Reboot your system and re-test. ERROR: "The Device Driver Is Already In Use" A. You are playing a music CD and have attempted to open a second copy of the Pocket CD utility. Press + to bring up the task list, select Pocket CD and click on "Switch To" to restore the original Pocket CD. ERROR: "Dyna Link Error" A. The MMMIXER.DLL file has been corrupt or is missing. A copy of this file resides within the PROGRAMS.LZH file in a compressed format. Create a temporary directory on the hard drive, copy the PROGRAMS.LZH and LHARC.EXE files to that directory. From your temporary directory, execute the following command. LHARC X PROGRAMS This will expand all compressed files, copy the MMMIXER.DLL to the WINDOWS/SYSTEM directory. ERROR: "Incorrect DOS version" during boot up and cannot access my CD-ROM drive A. Change the line in the autoexec.bat file with MSCDEX.EXE from: c:\proaudio\mscdex.exe /d:mvcd001 /m:10 /v to: c:\dos\mscdex.exe /d:mvcd001 /m:10 /v ERROR: "Insufficient memory" or 'Not Enough Memory" This error indicates that too much of you lower 640k of memory is being used by device drivers and/or memory resident programs. It does not mean you do not have enough 'ram' installed in your PC. It just that it is not configured correctly. This is commonly referred to as "Memory Management". There is no "Magic Answer" to memory management on your PC. It is strictly dependent on your hardware configuration, the drivers required and other software you are using. There are various reasons you may have not encountered this type of error until installing your Media Vision Product. The most common reasons are that you need to do your memory management in order to load your various drivers (including your new multimedia drivers) into high memory. This is no different than what would be required after installing any hardware item that uses device drivers. Secondly, Multimedia applications and games are notorious for being very large in size and routinely need over 580k of free conventional memory in order to run. It is easy to find some games that need over 600k. This memory requirement is significantly larger than most normal word processors or spreadsheet programs that might appear to be more complex. With a little work and some learning about your PC, most users can get the required amount of conventional memory freed up to run their multimedia applications. For DOS 5.0 users, refer to your DOS manual in the section discussing 'Optimizing Your System' for information on how to do your memory management. For DOS 6.0 (or higher) users, refer to the same section in your DOS manual and also learn about DOS's MEMMAKER program. Optionally, there are several 3rd party memory managers available on the market if you don't like the Microsoft utilities that came with your DOS. Your favorite computer center should have these available and should be able to make recommendations. Memory Management is not a function of your multi media kit and Media Vision can not maintain information on every possible hardware / software combination for every PC. It is also Media Vision's policy that we can not recommend 3rd party products as one may work great on your neighbor's PC and not at all on yours. In general terms, all of Media Vision's device drivers CAN be loaded into high memory, thus freeing up your conventional memory for programs. The techniques for accomplishing it vary from system to system. ERROR: "Invalid drive specification" WHY: This is a standard DOS error message that means that the drive letter that you are trying to access is not available on your system. A. LASTDRIVE= statement is not in the CONFIG.SYS file, or is set incorrectly. The parameter is the next logical drive letter after the letter that should be assigned to the CD-Rom drive. For example if you have one hard disk, and it is partitioned into two logical drives, those drives will be C: and D:. Your CD-Rom drive will install and be recognized as your E: drive. Therefor, your LASTDRIVE statement in the CONFIG.SYS file MUST be: LASTDRIVE=F: Refer to your DOS manual for LOGICAL DRIVES and MSCDEX.EXE B. The MSCDEX.EXE statement your AUTOEXEC.BAT file has an incorrect "/L:" parameter specified. The /L: parameter allows you to specify the drive letter you want to use for your CD-Rom drive. As in the example in 1. above, the parameter would be /L:E. In most cases it is best to leave off this parameter and allow DOS/MSCDEX to assume the next available drive letter. Refer to your DOS manual for LOGICAL DRIVES and MSCDEX.EXE C. Another driver or TSR is interfering with the TSLCDR.SYS or MSCDEX.EXE. Change to a generic CONFIG.SYS and AUTOEXEC.BAT files, reboot and re-test. D. The TSLCDR.SYS or MSCDEX.EXE did not load properly during boot up. This will normally have created an error message during loading. See "Basic Troubleshooting Steps" to check for boot up errors. ERROR: Memory Error Messages: See "Error: Insufficient Memory" ERROR: "Memory Parity Error" This is usually caused by a DMA conflict ERROR: No SCSI Host Adapter Found Why: This error indicates that the SCSI port on your PAS 16 could not initialize properly. A. With the power turned off, disconnect the SCSI cable from you CD-ROM drive. Turn the power back on and check for boot up errors. If the SCSI adapter is found, the SCSI port on the sound board and the SCSI cable are good. If you see a new error "No Devices Respond on This SCSI Host Adapter". This indicates that either the SCSI cable was connected backwards on the CD-ROM, the CD-ROM is bad, or the power connection on the CD-ROM is faulty. If you receive the same "No SCSI Host Adapter Found" error message, then disconnect the SCSI cable from the sound board and repeat the test. If you get the proper response "No Devices Respond on This SCSI Host Adapter" it indicates your SCSI cable may be bad. If the original error persists please contact Media Vision Technical Support. ERROR: "No Valid CD-ROM device" A. If you do not have a CD-ROM drive: 1. Edit the CONFIG.SYS file and add "REM" to the beginning of the line that says: device=c:\proaudio\tslcdr.sys /d:mvcd001 2. Edit the AUTOEXEC.BAT file and add REM to the beginning of the line that says: c:\proaudio\mscdex.exe /d:mvcd001 /m:10 /v B. If you do have a CD-Rom drive see 'Basic Troubleshooting" to test for boot up errors. ERROR: "No wave device that can play files in the current format is installed. Use the Drivers option to install the wave device." A. The .WAV file you are trying to play is not in the standard format and can not play with the utility or application you are attempting to use. To verify: Use the Pocket Recorder and play the sample wave files in the Windows or ProAudio directory to verify that .WAV files do play. If successful with the sample files, but you still can't play the file you want, try playing it with the application used to create the file originally. B. The .WAV file you are trying to use was recorded on the Pocket Recorder and saved with File Compression enabled. You must use the Pocket Recorder to play the file. ERROR: "A ProAudio Spectrum is not installed" A. Caused by the MVSOUND.SYS not loading. B. Try adding /w:0 to the end of the mvsound.sys line in the CONFIG.SYS file. C. Check the mvsound.sys line in the CONFIG.SYS file and delete the /U option if it is there. This option unloads the driver. D. See "Basic Troubleshooting Steps" to check for Boot Up Errors ERROR: "You may have a disc in your CD-Rom drive that contains both data and CD digital audio. Since data is usually stored on track o........" A. You are trying to play a data CD with the Pocket CD utility or Media Player's CD Audio. Only Music CDs (Redbook Audio / CD Audio) can be used with these utilities. ERROR: "You must load Multi Media Extensions" Windows Multi Media Extensions are not installed. Edit the SYSTEM.INI file in the windows directory and add the following lines IF they are missing, and insure there are no other parameters on the mmsystem.dll line. SOUND.DRV=MMSOUND.DRV DRIVERS=MMSYSTEM.DLL Install Program Locks Up Computer A. Frequently caused by encountering a DMA conflict while testing for available settings. Doing a partial manual installation of the sound driver will usually allow the installation program to run. Perform the following steps: At the dos prompt, type MD C:\PROAUDIO Insert the installation diskette in the drive and type: Copy A: or B:*.* C:\PROAUDIO Add the following line to the CONFIG.SYS DEVICE=C:\PROAUDIO \MVSOUND.SYS D:3 Q:7 S:0 M:0 T:1 /W:0 Reboot the computer then attempt to reinstall per the original instructions B. Change to a generic config.sys and autoexec.bat C. Remove any other interface boards (NOTE: you cannot remove your disk controller or video board) and try again. D. See document titled "PAS 16 D Manual Installation Instructions" IRQ: Interrupt request: a 'flag' sent up by a device to notify the CPU that it needs attention A. Valid IRQs are 0 through 15 B. Preferred IRQ for Pro Audio 16 is 10, 11, 12, or 15 C. Preferred IRQ for Sound blaster emulation is 5 or 7 D. Symptoms of IRQ conflicts 1. Wave Files have looping or echoing sound 2. No audio 3. Distorted audio 4. System "hangs" or locks up 5. Other device (mouse, modem, scanner, etc.) stops working. E. Determining what IRQs are available 1. Check documentation for you system / motherboard 2. Check documentation for each interface / controller board installed in your system. 3. Run MSD (Microsoft Diagnostics) or similar utility program to help determine what IRQs are already used.. Note: There are no known diagnostics that can 100% accurately report IRQ or DMA usage. Typically, they can only report IRQs used by BIOS driven devices. They are however somewhat useful as a starting point. It may be necessary (and sometimes quicker) to use the installation routine and find available settings through trial and error. F. See "DMA" G. See "Configuring / Re-Configuring You System" Jumpers: There are no jumpers on the PAS16 that can be changed. Looping: A condition where you hear a sound constantly repeating. Normally caused by an IRQ conflict MSCDEX.EXE: Microsoft CD-ROM Extensions - a program written by Microsoft to facilitate communications between your CD-Rom and the CD-Rom driver. Parameters that are supported are: D:x, where x is the same device name that is assigned to the CD-ROM device by TSLCDR.SYS. M:x, where x is the number of 2K memory buffers, 10 is usually used. L:x, where x is the drive letter you want to assign to the CD-ROM drive. V is for a verbose listing of information about memory usage. E is for expanded memory usage. MVSOUND.SYS: A. The DOS device driver that initializes the PAS 16 sound board. B. MVSOUND.SYS must load in the CONFIG.SYS file in order to properly initialize the sound board. C. It must be loaded in order to produce sound in most DOS applications. D. To unload the driver after it initializes the board, add "/U" to the end of the MVSOUND.SYS line in the config.sys file. SCSI Port: A. Type: Zilog's Z5380. B. Driver: TSLCDR.SYS C. Supported CD-Rom Drivers - contact Customer Service or Media Vision's BBS for the most recent CD-Rom Support list D. Max. transfer rate: 690KB/sec. E. Port is SCSI-1, however, with the TSLCDR.SYS version 3.12 or higher, SCSI-2 devices are supported F. Other SCSI devices: Support for SCSI hard drives, Scanners, Optical drives etc. are supported via a software product called "SCSI WORKS", produced by Trantor (Adaptec). Contact 1-800-TRANTOR for information. SCSI WORKS is NOT a Media Vision Product. Contact Trantor for support. Sound Blaster Emulation TO DISABLE SOUND BLASTER: Change S:1 to S:0 in CONFIG.SYS file on the MVSOUND.SYS device driver. This will disable the SOUND BLASTER's IRQ, I/O port and DMA 1. Sound Types A. Digital Audio: Recorded sounds, usually speech and sound effects. These sounds are produced by the Digital-To-Analog Converter (DAC) on the PAS16. WIN31 uses the file extension .WAV for digital audio. Some programs use the file extension .VOC for digital audio. B. Synthesized Audio: FM sounds, usually music but can also be used to produce speech and sound effects. These sounds are produced by the FM Synthesizer on the PAS16. WIN31 uses the file extension .MID for synthesized audio. C. CD-Audio: CD-Audio Red Book sounds. These sounds are produced by the CD-ROM drive, not by the sound board. D. PC Speaker: Crude music tones, speech and sound effects produced by the System Timer Chip on the motherboard. These sounds are played back by the internal PC Speaker. E. AdLib: AdLib sound card F. Sound Blaster: Sound Blaster sound card G. MPU-401: Roland's proprietary interface protocol for MIDI music. Hardware support for MPU-401 supports "UART (dumb mode)" only. (Requires additional IRQ and I/O port address) Sound Problem: No CD Audio (Music CDs), All other sound is fine. A. If your application (ie: Pocket CD, Media Player, Music Box, etc) says that the CD is Playing, but you have no sound: 1. Check the Pocket Mixer (or DOS mixer) to make sure the CD Audio volume control is turned up and is in 'play' mode. 2. Check that the Audio cable is properly connected. 3. Plug a set of headphones into the headphone jack on the front of the CD-Rom drive to make certain it is Red Book Audio. Sound Problem: Scratchy, Static, Noisy A. Edit the CONFIG.SYS file and add T:1 at the end of the line. Save the file and reboot the system. Consult page 67-68 of the PAS16 Installation Guide under for an explanation of the "T:1" switch. B. Change to another available DMA/IRQ combination (see RE-SELECTING HARDWARE SETTINGS. C. Contact Technical Support. TSLCDR.SYS - This is the SCSI CD-ROM driver used in Media Vision multi media kits with SCSI CD-Rom drives. Volume Too High / Too Low At Startup A. For Windows 3.1: Open the MAIN program group; open the CONTROL PANEL; and then open DRIVERS. Select "Media Vision Pro Audio/CDPC Mixer" and click on SETUP. Make sure that the selection "Inherit DOS Mixer Settings" is turned OFF (no 'x' in the box) and then click on the box that says "Save Windows Mixer Settings" to turn it on. You will be prompted to restart windows and select restart now. After Windows comes back up, open "Multi Media Tools" program, and open the Pocket Mixer. Adjust the mixer volumes to an appropriate level and test with Pocket Recorder or Media Player. the levels will remain at this settings. B. For DOS, there are two options: 1. Add the volume parameter to the MVSOUND.SYS line in the config.sys file. ex: device = c:\proaudio\mvsound.sys d:3 q:7 s:1,220,1,5 m:0 j:1 v:75. The "v:75" forces the startup volume to be at 75%. The range is 0 to 100 2. Start up the DOS mixer by typing PAS * at the command line. Adjust the volume settings to an appropriate level and then save the settings by pressing SHIFT+F5. Edit your autoexec.bat file and add the line "c:\proaudio\pas f5". This will recall the settings you saved, each time your system restarts. Volume: Saving Volume Control Settings A. See fix for "Volume Too High / Low At Startup" Windows Hangs While Exiting A. Typically caused by an IRQ Conflict. See "Configuring/Re-Configuring your system" B. Temporarily turn off the Window Exit Sound while troubleshooting: Open the MAIN program group; open the CONTROL PANEL; and open SOUNDS. Select "Windows Exit" from the left side box then select "None" from the right side box.
