I have SoundBlaster Live! Digital (emu10k1) and after upgrading from fedora 9 to fedora 10 PulseAudio starts sometimes drop sound for sec. Befora upgrading PulseAudio dropout only when I use firefox, now even if system do nothing. this is output from pulseaudio -vvvvv: I: module-alsa-sink.c: Underrun! N: module-alsa-sink.c: Increasing wakeup watermark to 40,00 ms D: protocol-native.c: Requesting rewind due to end of underrun. D: module-alsa-sink.c: Requested to rewind 30784 bytes. D: module-alsa-sink.c: Limited to 24080 bytes. D: module-alsa-sink.c: before: 6020 D: module-alsa-sink.c: after: 6020 D: module-alsa-sink.c: Rewound 24080 bytes. D: sink.c: Processing rewind... D: sink-input.c: Have to rewind 24080 bytes on render memblockq.
Created attachment 325058 [details] pulseaudio -vvvv debug log I can confirm this issue on Fedora 10 (x86_64) and a Soundblaster Live 512 card (same driver). The attachment is the debug log from running $ pulseaudio -vvvv Of course, when I did this by hand it rarely skipped (thus you can see several song plays through Rhythmbox before the "Underrun!" message at the end). In daemon mode, the skipping seems to occur more often. Also, adding PolicyKit permissions to run PulseAudio in Realtime/high-priority mode didn't appear to do much. Versions: alsa-lib-1.0.18-6.rc3.fc10.x86_64 pulseaudio-0.9.13-6.fc10.x86_64
I should have looked around more -- this appears to be a Duplicate of bug 462026.
