 A little more documentation indicates how to get the PPA and the also 
 driver modules package FOR YOUR KERNEL!
 https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules

 In reference to getting HDMI on other cards, generally a way to go 
 about it is to launch VLC or some other audio player with good audio 
 config tools.

 (remember to use alsamixer to ensure the digital output devices are not 
 muted)

 Generally I start an .MP3 in VLC and then jump into the VLC audio 
 control panel, select the ALSA output (under Advanced) and then switch 
 between the various audio card/device combos until the sound is 
 available.  then you make note of the card+device combo.  You should be 
 able to select/configure for that distinct combination in the Myth audio 
 setup (no need to mess around with .asoundrc or other alsa config files)

 I'm sure some more seasoned vets will advocate simpler ways using 
 speaker-test to find the right HDMI audio output combo, but this works 
 for me.

 In deference to JYA's efforts, I still have never gotten Myth 0.23-0.24 
 to pickup a default configged device for HDMI audio, I've always had to 
 manually config.

 Cheers.
