<font size="+1"><font face="Times New Roman">Ok, I tried it this
morning after everything had been off for at least 12 hours, the
sound came on properly and lasted about 30 minutes. When it
died, the settings still pointed to ALSA:hdmi card 0 and a
speaker test was successful. I exited the FE and checked
alsamixer which showed the correct settings and was not muted. I
restarted the FE and the sound was correct and lasted for about
20 minutes. When it went out I checked the settings, still
ALSA:HDMI card 0, speaker test was still successful, and after
exiting the FE, alsamixer showed the sound was not muted. This
time when I restarted the FE, there was no sound.<br>
<br>
I'm beginning to suspect a hardware issue, especially since an
identical AD-03 in a different room but connecting to the same
BE has delivered proper sound with no problems.<br>

operation, one FE (a Zotac ZBOX AD-03 with Mythbuntu 12.04

watching live tv. Checking the log produced 4 errors
together at the time when the sound was dropped:<br>
ALSA: Setting hardware audio buffer size to 128<br>
ALSA: Error opening
/proc/asound/card0/pcm3p/suub0/prealloc: Permission

ALSA: Try to manually increase audio buffer with: echo 128

I can restart the FE and the same scenario will repeat,
some amount of time with completely normal sound followed
by silence. Those 4 items will be in the log at the exact
time the sound fails.<br>
<br>
If someone is familiar with this situation and can offer
suggestions that would be great.<br>

<div>Those messages are harmless. You can ignore them. </div>

</div>
<div>Make sure the audio device didn't change in the settings, and
that it's not muted using the alsa-mixer utility</div>
