Hi Conrad,

I did some minimal porting to 2.4.0 (just make it compile) and will
(perhaps this evening?) port your changes to the 2.4 Version of dmasound
(the split up one (dmasound_awacs.c & co)). And I plan to compare the code
with Darwin's.
Yes, I was able to turn off sound by fiddling with the mixer, but no way to
turn it on again ... (I did not yet look at the feature bits)
And changing the pcm2 volume in aumix changed the balance (indicates a bug
somewhere ...)

Here's the minimal patch for 2.4 to make it compile

Christof
