[mythtv-users] Audio dropouts after upgrade to 0.24

[Enigma]

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 19:10:34.978 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?
