[mythtv-users] No audio; two weeks and still unsolved

[Jeff Bevis]

Mike, thanks for your quick response to my plea for help ;-)  
Unfortunately, it was a no-go.  ""Mixer controls master" yielded:

==============

Can't find control "Master" either.  No PCM, no Master.  What's going on 
here?  How can I find out what the mixer /does/ have in the way of 
controls?  This is just an NVidia NForce4 chipset, is there not support 
for this (hard to believe)?!  Well wait, command line aplay works, 
alsamixer too.  I'm back to square one.  Where do I go from here, start 
writing a volume control script?  That seems unlikely to be the right 
action...  My gut is telling me something else is wrong, and I just 
don't know where to look.
