" Indeed I have been following your posts from the start. It seemed

were not making any progress; I have suggested a way to proceed.

If you can see all the details of all the controls on the sound card,
via Mixer Browser or whatever, you should be able to control them
using the standard mixer API. I suspect that once you see "the big
picture" you will have a better idea of why your current approach
doesn't work. It certainly won't hurt to take a look, and if you
find
something unexpected you can share it with the rest of us. "


Vinay: What was the way you suggested, I might not have got it. Can
you explain it to me once again ?

You need to see what controls are exposed to the mixer API, and where
they are located. I have found that it's best to use a separate app
that shows everything the mixer can access, including destinations,
sources, and controls. The mixer layouts changed drastically from
Win9x to XP, and from XP to Vista. If you can see the whole layout,
you can determine how to access the control you want. It might not be
available to you at all... depends upon the driver implementation.

You might also try running your app in XP compatibility mode under
Vista, which may expose a different set of controls. (It does on my
system... see my new thread "MixList v6.60 and Realtek issues".)

Again, I use Mixer Browser and/or my own MixList to see the full
mixer. You can Google for Mixer Browser. MixList is at
