OPTi 82C924 Windows 95 Drivers
Version 4.00.20
12/06/95
UPDATE NOTES
This latest version is an update from version 4.00.10 and
contains the following updates:
1) Bug fix for recording using Single DMA Channel
2) Bug fix for Sound Blaster Stereo effect in DOS Box
INSTALLATION PROCESS
If you do not have a previous copy of the drivers installed, and
you are installing this Sound Card plus Driver package for the
first time, you may proceed to the FIRST TIME INSTALLATION section.
However, if you are updating your previous installed drivers, you
MUST follow the UPDATE PREVIOUS DRIVERS section below in order to
succesfully install the new drivers.
UPDATING PREVIOUS DRIVERS
[Updating "OPTi Plug-N-Play Sound System" Driver]
1. You should have the latest drivers on a floppy diskette ready
for installation.
2. Start Windows 95 and proceed to the Control Panel folder and
select (double click) the Add New Hardware icon. This will
add/update the OPTi Sound Device and it's associated drivers.
3. When prompted by Windows 95 for the Auto-Scan option for
detecting new devices on your System - select NO and proceed
to the next page.
4. Windows 95 will display a list of known devices that you
currently wish to install. Select "Other Devices" eventhough
the name of the device is included in the list. This forces
Windows 95 to perform a fresh install for your device. Select
Next to proceed.
5. Windows 95 will again display a list containing manufacturer
names and at which point you should ignore the list and select
the "Have Disk..." button. This tells Windows 95 to read
special installation instructions from your diskette to
correctly install the drivers for your OPTi Sound device.
You will have to direct Windows 95 to the proper location of
the floppy diskette.
6. Once information from the floppy diskette has been read by
Windows 95, a list of devices available for installation will
be displayed. This list contains driver setup options pertaining
to your Sound Card's capabilities. For example, if your Sound
Card has an IDE CD-ROM interface which you wish to connect your
IDE CD-ROM to, select the appropriate option to enable this
setup. If your Sound Card does not contain any options other
than Audio functions, then just select the first option.
7. Windows 95 will now proceed to install the drivers needed for
your device and configure your device accordingly. Once your
device has been successfully configured, Windows 95 will prompt
you to restart your system - select Yes for the new drivers to
take effect. YOU MUST REBOOT for the changes to take effect!
8. Install REAL MODE DOS Support: During the system reboot process
the DOS Installer will be invoked automatically. Please follow
the instruction of DOS Installer and it will setup the sound
card properly for the Real Mode DOS games or applications.
FIRST TIME INSTALLATION
Install the Sound Card into your system and reboot your machine;
Windows 95 should detect new PnP resource on your Sound Card and
prompt you for the installation files. At this point, insert the
OPTi 82C924 Windows 95 Driver diskette into your floppy drive and
let Windows 95's Device Manager direct you through the installation
of the drivers.
When Device Manager finds a new device but cannot determine/find the
correct driver for the device, it will prompt you for the location
of the drivers associated with the device and will expect that the
drivers are from a floppy diskette. At this time, select OK if the
option "Drivers from disk..." is enabled and Device Manager will
proceed to copy the drivers from the diskette. However, if the option
"Windows Compatible Driver" is enabled, select OK as well to direct
Device Manager to make use of default drivers for that particular
device.
RECONFIGURATION OF RESOURCES
The OPTi 82C924 device is a fully Plug-n-Play device and all it's
resources should be reconfigurable on-the-fly unless due to a
similar conflicting device present in the system.
To reconfigure the resources, use the SYSTEM icon located in your
Control Panel folder and choose Device Manager. From Device Manager,
double click the "OPTi Plug-N-Play Sound System" option and the
list of installed OPTi Audio devices will be displayed. Double click
on the device which you wish to change resources for. Once resources
have been changed, the driver will be automatically reconfigured to
operate with the new resources and function as before.
AUDIO SUPPORT under REAL MODE DOS
[Systems with Win95/DOS Setup]
To enable support for DOS Games or multimedia applications under
a REAL MODE DOS environment, please follow the Step 8 of INSTALL
PROCESS. If you decide not to do DOS setup now, it's OK to skip it.
Type C:\SND4DOS at real mode DOS prompt at any time will bring up
the DOS Installer.
[Systems with Dual Boot Win95/Win31 Setup]
Please run OPTi's Win31/DOS Install package at Real Mode DOS
prompt. When prompted during the installation for the path to
your Windows directory, specify the path if you have Windows
3.1 installed on your system (under a seperate directory from
Windows 95). Select None if you do not have Windows 3.1 installed.
AUDIO SUPPORT under WINDOWS 95 DOS BOX
DOS Game support has been added for this release and is fully
functional. During the setup for your DOS games, you must ensure that
the current resources assigned to the sound card matches with the
current settings requested by your DOS game. To find out what resources
are currently assigned to the sound card, proceed to open the properties
box associated with the "OPTi Plug-N-Play Sound System" (Device Manager)
and select the Resource tab. From the Resources box, you should see the
current I/O Address range for Input/Output Range Number 1. We recommend
the 220 Hex address range as opposed to the 240 Hex be selected as most
games support 220 Hex by default. We also recommend the Interrupt and
Direct Memory Access settings of 7 and 1 respectively. Reconfigure these
resources as appropriate and select OK for Device Manager to dynamically
change and update your current resources and configure the hardware.
At this point, you may setup your DOS game with the settings which you
have just configured.
Also, if you have a Wave Table Device on board or attached to your
sound card, you should also follow the recommended steps above but
this time check on the "OPTi Plug-N-Play MPU-401" device settings
instead. You will need it's current settings if you wish to enable
General MIDI support in your DOS games.
To ensure an ideal environment for DOS games, it is recommended that
you modify the Idle Sensitivity property of your DOS Game environment
to High. To do this, press the ALT+ENTER keys to change to a DOS Box
Window (if not already in a Windowed session) and click on the top left
hand corner of the DOS Box Window. A drop down menu will appear and
at which point you should select Properties. Select the Misc tab and
proceed to modify the above mentioned property.
HOT-KEY SUPPORT under WINDOWS 95 DOS BOX
The following are the Hot-Keys and their associated channel controls.
<CNTRL>+<ALT>+M = Decrease Master Volume
<SHIFT>+<ALT>+M = Increase Master Volume
<CNTRL>+<SHIFT>+M = Mute Master Volume
<CNTRL>+<ALT>+V = Decrease Voice (Digital Sound) Volume
<SHIFT>+<ALT>+V = Increase Voice (Digital Sound) Volume
<CNTRL>+<SHIFT>+V = Mute Voice (Digital Sound) Volume
<CNTRL>+<ALT>+F = Decrease FM Music Volume
<SHIFT>+<ALT>+F = Increase FM Music Volume
<CNTRL>+<SHIFT>+F = Mute FM Music Volume
FULL-DUPLEX DUAL-DMA SUPPORT
To enable Dual-DMA channel operation for simultaneous playback and
recording, please ensure the following:
1. The DMA resource settings under Device Manager must be different
and paired as follows:
Playback DMA: 0 1 3
Recording DMA: 1 0 0
2. The frequency format (eg. 11KHz, 22KHz..) must be the same during
simultaneous playback and recording.
3. Full-Duplex is only supported if you have CS4231/CS4248 Class CODECs
interfaced with the 82C924 PnP Audio Controller.
KARAOKE SUPPORT
The customizeable option for supporting Karaoke Sing-A-Long basically
turns on the LoopBack channel of the AD1848 class CODEC as well as
forcing the input MUX to Microphone. This will ensure that the ADC
signal is properly fed back to the output channel for amplification
using the DAC volume control. The following options may be specified
in the CUSTOM.AddReg section of the INF file.
To enable support for Karaoke Sing-A-Long, the following must be
specified:
..,Karaoke_Src_Name,,"Voice"
To customize default settings for the Mic input gain plus the Loopback
attenuation, the following must be specified:
..,"LeftKaraokeMicVol",1,0080 // Low Byte then High Byte
..,"RightKaraokeMicVol",1,0080
..,"KaraokeLoopBackVol",1,FFFF
Valid range is from 0000 -> FFFF ( 0 to 64K )
MIXER CUSTOMIZATION
Mixer driver customization info should be specified in the SND924P.INF
file which is located in the installation diskette and is required by
Windows 95 during installation of the drivers.
By default, this file instructs the Mixer driver not to support
any customizations and only the manufacturer's default channel
mappings and controls are supported.
To enable mixer customizations, proceed to the [CUSTOM.AddReg]
section in this file and modify the "Default_Codec_Mapping"
field from "Yes" to "No". This tells the mixer driver not to
use the manufacturer's default mixer mappings but to expect
customized channels mappings and controls instead.
TYPE 1) Channel Mapping Customization
The following are defaults:
..,AUX1_Src_Name,,"CD" // For AUX 1 Channel
..,AUX2_Src_Name,,"Synth" // For AUX 2 Channel
..,DAC_Src_Name,,"Wave" // For LOC and ROC channels
..,MIX_Src_Name,,"Mix" // For loopback Mix Channel
..,Karaoke_Src_Name,,"Voice" // For enabling Karaoke
Below are supported only if you have the extended CODEC on board
such as CS4231 or AD1845.
..,LINE_Src_Name,,"Line" // For LINE Channel
..,MIC_Src_Name,,"Mic" // For Microphone Channel
// Supported by AD1845 Only
..,MONOIN_Src_Name,,"Alarm" //
Channel mapping customization allows renaming of a source to
a different name thus changing the original assumed source
mapping of the channel.
TYPE 2) Extra internal controls through existing H/W resource
- for controls using general purpose output bits of CODEC
or MC device.
These internal controls are of the ON/OFF type controlled by a
single toggling bit.
The following are valid:
..,Total_Internal_Controls,1,n // Total number of controls desired,
// maximum is 3.
// Default is assumed to be none.
..,Internal_Control_1_Name,,"SRS-3D" // Name to call this control.
..,Internal_Control_1_OnVal,1,00 or 01 // What is the default ON bit.
// Default is 01.
..,Internal_Control_1_By,,"XCTL0" | "XCTL1" | "GPOUT"
// What bits to use for control based on the following
// available on the default H/W.
XCTL0 - OUT 0 bit located at index 10 of CODEC registers
XCTL1 - OUT 1 bit located at index 10 of CODEC registers
GPOUT - General Purpose Output bit at MC4
..,Internal_Control_2_Name,,""
..,Internal_Control_2_OnVal,1,00 or 01
..,Internal_Control_2_By,,""
.
.
..,Internal_Control_n_Name,,""
..,Internal_Control_n_OnVal,1,00 or 01
..,Internal_Control_n_By,,""
TYPE 3) Extra external controls through external logic
(Requires DLL from third party).
..,Total_External_Controls,1,n // Total number of controls desired,
// maximum is 3.
// Default is assumed to be none.
..,External_Control_1_Name,,"SRS-3D" // Name to call this control.
..,External_Control_1_By,,"XCONT_1.DLL" // The accompanying DLL. Each
// external control has it's own
// unique DLL.
..,External_Control_2_Name,,"" // Name to call this control.
..,External_Control_2_By,,"XCONT_2.DLL"
..,External_Control_3_Name,,"" // Name to call this control.
..,External_Control_3_By,,"XCONT_3.DLL"
Each external control has it's own set of exported functions for
the driver to call. For example, external control 1 will have the
following 3 functions:
XControl_1_Init();
XControl_1_On();
XControl_1_Off();
The accompanying DLL must explicitly export these functions exactly
as named above.
** NOTES **
1) Internal and External Controls must be of the ON/OFF control types;
any other types are not supported for now.
2) In order to make use of the ON/OFF controls in the Volume Control
application bundled with Windows 95, you will have to enable the
"Advance Controls" option under the "Properties" menu item.
