You may want to check what the output of unimix -list > mixer.txt shows (unimix.exe is a command line mixer which you should find in \MMOS2)....
Hope the above helps.

Having first checked the bios and then the OS/2 hardware manager I tried unimix.exe as follows with disappointing results.

[C:\]unimix.exe -list
Command line mixer for UNIAUD32. Version 1.1
Detected UNIAUD version 2.02.01
Detected 2 audio adapter(s)
Error: invalid number of PCM instances for adapter 0
Control list for adapter 0

Any thoughts?

Thanks


Joe

As you have two cards, you need a newer unimix. download latest driver from http://svn.netlabs.org/uniaud

Joseph M. Kempf:
Thanks for this advice Silvan.

The version of unimix.exe included in the most recent uniaud update package was created on 9/22/2010.  The version that shipped and installed with eCS beta 2.2 was created on 9/23/2013 and is thus three years newer.

The older version produced the following error message.
[C:\]unimix.exe -list
Command line mixer for UNIAUD32. Versio
Detected UNIAUD version 202.01
Error: invalid number of PCM instances

It seems as though I'm going to learn a bit more about uniaud.  Webpage http://trac.netlabs.org/uniaud states:

--- Quote ---The latest beta version of Uniaud32 is 2.02.01 which is based on ALSA 1.0.24. This version has had very little testing. It is currently unknown if there are any problems with this version. Try it at your own risk and backup first

My version is the beta 2.02.01.  I may have to install an earlier stable version, say maybe: Uniaud32 v.1.9.26 

Should I install two sets of uniaud drivers, one for each on-board sound chip?

BTW: I tested it on an ASUS A88x-Plus motherboard and generally find eCS beta v2.2 much to my liking.

Can anyone tell what is a "PCM instance"? ;-)

Ok so latest beta seems to bring latest unimix.
What does your unimix -card show?

I had a moment to run the newer version of unimix on my ASUS A88X and this is the result:


--- Quote ---[C:\]unimix.exe -list
Command line mixer for UNIAUD32. Version 1.1
Detected UNIAUD version 2.02.01
Detected 2 audio adapter(s)
Error: invalid number of PCM instances for adapter 0
Control list for adapter 0

As you can see unimix.exe properly identifies the version of uniaud32 that ships with  eCS v2.2 beta.  It detects the two on board audio "adapters".  Then it reports an error I do not understand.

Thanks

Joe
