Hi
My problem started when I did not get any sound from a fresh installed
MythTV on my FC2 system. I then found the
http://www.mythtv.info/moin.cgi/DigitalSoundHowTo but even though I have
the same hardware Asus A7N8X-Deluxe this .asoundrc will not work for me
out of the box. Here is my problem.
When using aplay with mixed-analog "aplay -D mixed-analog
/media/music/slask.wav" or using mplayer "mplayer -ao alsa1x:
mixed-analog /media/music/slask.wav" I do not get any sound. All the
other three devices analog, digital and mixed-digital works though. If I
change the rate in dmix-analog to 44100 it works though (are there any
drawbacks doing this?)
Using mplayer to play a dvd "mplayer dvd://1 -ao alsa1x:mixed-analog"
does - not surprisingly - work but as a surprise the device analog does
not work either. The devices digital and mixed-digital do work.
Here follows some diagnostic output. Is there anything else relevant? Do
alsa write a log file somewhere?

Maybe this problem should be in the alsa-user mailing list but since I
am trying the above mentioned DigitalSoundHowTo I decided to start out
here.
Any hints???
