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>

FE (a Zotac ZBOX AD-03 with Mythbuntu 12.04
0.25/fixes) suddenly dropped sound completely while
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
denied.<br>
ALSA: Try to manually increase audio buffer with: echo
128 | sudo tee /proc/asound/card0/pcm3p/sub0/prealloc<br>
ALSA: Unable to sufficiently increase ALSA hardware
buffer size - underruns are likely<br>
<br>
<br>
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>
<br>
<br>
<span style=" font-family:'courier new'; font-size:

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

<span style=" font-family:'Courier New'; font-size: 9pt;">It can
also be an issue on your backend. Check if old recordings, you
know to contain sound, produce sound.<br>
Also you can check if the files that failed to produce sound, do
contain sound by playing them in another context.<br>
If not the problem is probably either with your hardware (the
encoder of your card) or with your encoding profile<br>
or the encoding software.<br>

I picked a recording where the sound went quiet, bookmarked the spot
and resumed play on another identical machine, perfect sound.
Neither the profile nor the software has changed. I've been looking
for an excuse to use a machine with Nvidia instead of ATI graphics
anyway.<span class="moz-smiley-s3"><span> ;-) </span></span><br>
