I should also add, the effect we see when running that aplay command
again, to do a simple WAV play is: no errors, everything looks like it
does on a good system where the test works, but the result is no sound.

Title:
  11.04 HDMI audio doesn't work

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  New

Bug description:
  HDMI audio works fine with all of my hardware when running 10.04 or
  10.10, with minimum tweaks to get it going from a fresh install.  I
  have to build an /etc/asound.conf file and use alsamixer to unmute and
  turn up several volume settings and that's it, then this command will
  play a test sound over the HDMI:

    aplay -D plughw:0,3 /usr/share/sounds/alsa/Noise.wav

  I've spent a good two hours and launched this thread with much more
  detail about the problem at ubuntu forums.  There are at least two
  others posters to that thread in the same situation as me.

  My motherboard is a Biostar TForce TF70505-M2, with onboard HDMI,
  details here:

  I'd appreciate seeing a fix on this and am willing to help out with a
  bit of testing.  I'm getting close to just rolling back to 10.10 for
  now though.
