I have no experience with your specific motherboard and its audio hardware; 
however, I do have several suggestions/comments:

- There are several MythTV wiki entries on sound, including
  http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound,
http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound_with_AC3_and_SPDIF,
  http://www.mythtv.org/wiki/index.php/Sound_card, and
  http://www.mythtv.org/wiki/index.php/Sound_Troubleshooting. Read them all.

- Unfortunately, mixer settings vary from one sound card to another, so
  the correct settings for one computer may not be the same as the correct
  settings for another. You'll have to experiment.

- Try to get sound working OUTSIDE of MythTV first. It's easier to adjust and
  test things like sound output devices using tools such as play and aplay
  than to do so in MythTV.

- Some people find that using ALSA output specifications for sound works
  better than using OSS device files, but the OSS device files work fine
  for others. Again, you'll just need to experiment.
