Audio dropouts after upgrade to 0.24

I recently upgraded my 6 machine myth system to 0.24 and I am experiencing
several problems. On one of my frontends the audio is dropping out
occasionally when playing back h264 material from a HD-PVR (PVR-xxx MPEG and
OTA MPEG do not seem to have the same issue, nor does Mythmusic). This
machine is using analog stereo output and VDPAU video output. After
upgrading the box I went into settings and scanned for audio devices,
ALSA:Default no longer works or appears in the scan (but does work as an
output device with aplay) so I chose the option that seemed to be the
closest which is ALSA:front:CARD=ICH5,DEV=0. I also see the same behavior
using /dev/dsp. Using the default logging options myth does not write
anything relevant to the issue but if I use -v audio I get some output that
may be relevant. When the dropouts happen this is what is printed to the
log:

2010-12-06 19:10:07.504 AO: Pause 1
2010-12-06 19:10:07.511 AO: OutputAudioLoop: audio paused
2010-12-06 19:10:07.526 AO: Pause 0
2010-12-06 19:10:07.573 AO: OutputAudioLoop: Play Event
2010-12-06 19:10:34.969 AO: Pause 1
2010-12-06 19:10:34.978 AO: OutputAudioLoop: audio paused
2010-12-06 19:10:34.991 AO: Pause 0
2010-12-06 19:10:35.038 AO: OutputAudioLoop: Play Event
2010-12-06 19:10:54.459 AO: Pause 1
2010-12-06 19:10:54.468 AO: OutputAudioLoop: audio paused
2010-12-06 19:10:54.481 AO: Pause 0
2010-12-06 19:10:54.529 AO: OutputAudioLoop: Play Event


According to lspci the audio device is:
00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller (rev 02)

Can anyone recommend steps I can take to debug or resolve this issue?

Hi

Post the log with -v audio,playback

those logs do not show anything special, just that you either paused,
or the player asked to pause the audio

Hmm, I tried to post the log for a minute of playback but it got
bounced because it was too big.  Here is the first half:

This is the culprit:
Player(0): Waiting for video buffers...

so the player pause the audio, before resuming...

Try to increase the size of the VDPAU buffer, and if that's not enough

If you could post a short sample somewhere, and raise a ticket on trac
to see if it's a similar issue to what have been earler reported with
some VDPAU playback.

I have set vdpaubuffersize to various values from 2-50 with no apparent
change. I also enabled vdpauskipchroma and disabled deinterlacing. The
TripleBuffer option is set to true in xorg.conf (and of course I have
compositing disabled). Nothing seems to change the issue.

This is a little frustrating because this machine worked fine under 0.23.
Were there major VDPAU changes for 0.24? I am using the same Nvidia drivers
and the same kernel as previously, the only thing that has changed is my
MythTV version and its dependencies. I would have just stayed at 0.23 but
the backend would deadlock fairly frequently (changeset 26827). Are there
any other options I can try to address this issue? This does not seem to be
too widespread, I have only seen one other post to the list that seems to be
the same issue. What are the chances of this issue being addressed? Is
this a regression in 0.24 or was I just getting lucky that it worked
before? This machine is not powerful enough to decode h264 in software - is
this likely to be another example of hardware that is no longer supported by
Myth?

the chances of getting it looked at would increase if you submitted a
bug report with a sample on trac (https://svn.mythtv.org)

That link doesn't seem to go anywhere (and http://svn.mythtv.org just
says "This is a placeholder") but after finding Trac I was able to
submit the bug: http://svn.mythtv.org/trac/ticket/9344.  Thank you for
your help Jean-Yves.
