I had pretty much the same problem recently.  A good friend gave me this advice:


You need to look into using the "dmix" functionality of ALSA instead of the deprecated (on 2.6 kernels) OSS sound platform.

Look at http://www.mythtv.info/moin.cgi/DigitalSoundHowTo to see about
setting up an .asoundrc. Mostly you download the one he provides and
probably change the "device" parts inside it to correspond to your
digital output. Also uncomment the appropriate line to pick what you
want as "default".

Then type this in as the sound device in myth "ALSA:mixed-analog".


I did this and used the appropriate tests to make sure I didn't mess anything up inadvertantly. I did:
% aplay -D mixed-analog $HOME/english.au


I was able to hear it and assumed it worked, but when I use ALSA:mixed-analog with MythTV, I still get no sound when playing back recordings or watching live tv.

To use Myth's volume control with ALSA it's as simple as
putting "mixed-analog" (as opposed to "ALSA:mixed-analog" in the sound
device part) in the mixer device setting. I left "Master" in the
control part.


I tried to use external mixer settings and doing this. Neither seemed to help my situation.

In /etc/mplayer.conf, set "ao=alsa:device=mixed-analog"

If you use arts in KDE (which is the default), tell it to use the
mixed-analog too.  Go into sound system settings, force it to use
ALSA, and override the device location and put mixed-analog in there.

Then go ahead and play some Metallica in noatun or Juk while you watch
TV or a recording. Listen the sounds mix!



Hope this helps.


Thanks much for the input. I believe it set me in the right path. I hope I can work this out soon. So frustrating.


If anytone else can help, I'd greatly appreciate it.
