OSMMSNDF - SOUND FILES DO NOT PLAY TO COMPLETION IN OS/2 2.1, OS/2 2.11
02/05/96
=======================================================================
Sound Files Do Not Play to Completion in OS/2 2.1 and OS/2 2.11
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
One of the following occurs:
* Sound starts OK, but does end successfully.
* Sound starts OK in one session, but does not continue when sessions
are switched.
* Sound repeats when it shouldn't.
RESOLUTION
Make sure the interrupt level, I/O addresses, and DMA channel for the
sound adapter match the values in the CONFIG.SYS files, and that these
values do not conflict with values of other adapters in the system.
Sound Blaster adapters have jumper-selectable interrupt levels, I/O
addresses, and DMA channels. For the device driver and adapter to be
synchronized, the CONFIG.SYS file parameters must be set to match the
jumper settings.
Details about jumper selections are in the documentation that comes
with the adapter.
For an 8-bit sound adapter, a DEVICE statement in the CONFIG.SYS file
might look like the this:
DEVICE=C:\MMOS2\SBXXXXX.SYS 1 1 5 220 4 /N:MYDEVICE /Q
The general format of the statement is:
DEVICE=C:\MMOS2\SBXXXXX.SYS audio dma int ioaddr buffsize
/N:ddname /?
Where:
audio = Audio device number; usually 1.
dma = DMA Channel used by the SB card; usually 1.
int = Interrupt Level used by the SB card; usually 5 or 7.
ioaddr = I/O Address used by the SB card; usually 220.
buffsize = I/O Buffer size in KB; usually 4.
ddname = Device driver name used by the MMPM/2 audio subsystem.
? = /Q for quiet mode (no error messages displayed), or
/V for view mode (error messages displayed)
Note: The DSP level of the adapter must be 2.0 or greater. The level
can be verified by running test programs, such as TESTPMCV.EXE,
that are shipped with the hardware.
