Title:
Audio gaps and runaway logging after a while
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
Ubuntu 12.04
Behavior started after the last update from update-manager (which updated
pulseaudio).
Preconditions:
Playing video+audio from Hauppauge PVR250 TV capture card, which
intermittently stutters in audio/video delivery (half-second pause)
Symptoms:
After a while, the occasional stutter from audio delivery turns into a
2-second repeat - like a scratched audio cd, and pulseaudio starts logging lots
and lots of:
(3628.790| 0.000) D: [pulseaudio] module-udev-detect.c: /dev/snd/controlC0
is accessible: yes
(3628.811| 0.021) D: [pulseaudio] module-udev-detect.c: /dev/snd/controlC2
is accessible: yes
(about 10-100 rows each second) which does not stop.
I.e - every few minutes, the audio stops and repeats for a couple of
seconds, and then resumes normal operation, but seems to still be
stuck in some loop causing above logging.
Might be alsa-related, because:
- Restart of pulseaudio does not remedy the problem
- Stopping pulseaudio and continuing with alsa-only, still produces the
2-second pauses, but with silence instead of repeating audio.
This behavior was not present before the update.
