[Bug 1039441] New: pulseaudio loses sound
http://bugzilla.opensuse.org/show_bug.cgi?id=1039441 Bug ID: 1039441 Summary: pulseaudio loses sound Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: msuchanek@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Often after resuming from suspend sound is not working. Pulseaudio uses the dummy output and no hardware output is shown as alternative. Another strange thing I noticed is headphones are muted when plugged in. In testing plugging in headphones mutes speaker and unmutes headphones and unplugging does the reverse but the system is in state with headphones plugged and speakers unmuted. I don't know if some timeout fires when the system is suspended or the suspend has nothing to do with it and I just happen to check sound on resume. I have no idea how to debug this. -- You are receiving this mail because: You are on the CC list for the bug.

I tried some debugging guide after some fiddling I got into a state when pulseaudio was still not working and aplay was failing due to device busy.
In that case, you can run like pasuspender -- aplay -Dsysdefault foo.wav If this still gives EBUSY, it means something else is blocking. Check via fuser -v /dev/snd/*.
Unfortunately, I already got the system into working state so I cannot recheck I had the correct device and whatnot.

The recent kernel removes sysfs entries recursively, but the driver seems still trying to remove the individual entries that have been already removed. If my guess is correct, it should be merely harmless warnings. -- You are receiving this mail because: You are on the CC list for the bug.
