Howdy Scott,
Two things:
1. someone previously has mentioned that they have to use aplay -D or
speakertest or something similar outside of MythTV before Myth will
play nicely. The only reason I noticed this was because the first
many times I was trying to get HDMI audio working, it seemed like I
had to do something similar anytime I booted up the box. I had very
little spare time to really play around with it though, and since
early or mid February, it has worked everytime. I don't know if I'm
booting differently now or what.
2. Ubuntu users can get up-to-date ALSA via PPA, which I assume would
fix the kernel update issue (I haven't updated kernels in quite a
while): https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules
If the PPA updates too frequently, you could always update and once
you have it working, disable the PPA. That's what I did.
Have fun,
Marc
