Hi Martin P!  Welcome.

The same mechanism won't work for both XP and the older OSes.  However, the 
ac97 sample did at one time contain a way to expose multiple sliders for 
multi-channel, with a topology-mixerline workaround.  I believe that code may 
still be in the sample.

Subject: [wdmaudiodev] Multichannel Mixer Volume Control


Hi everyone,
There is a possibility to control different speaker volumes in a  
multichannel device under windows XP, however under other OS like 98, ME,  
and W2K only stereo speakers are visible by the windows mixer. Is there a  
way to acces the different channels under those OS? Thanks all.
Martin
