I'm attaching part of my syslog with Pulse started in Debug mode. The block is exactly when the issue started.
I need to mention also that without alsa the issue appears as a short silence. With alsa, the issue is like a scratched CD. When I say with or without is alsa installed or removed. Hopefully this helps. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1016825/+attachment/3412606/+files/syslog -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1016825 Title: Audio gaps and runaway logging after a while Status in “alsa-driver” package in Ubuntu: Confirmed 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.
