Could you try to update only pulseaudio (and related) packages? I'd like to know whether it's an issue of PA itself or anything else.

Thanks for the quick answer. There hasn't been a PA update in any snapshots since then so it's probably another package. I'm trying to single out the package update that introduced this bug for me, but there are over a thousand package updates I'm sifting through so it could take a while.

I found the culprit in libxcb1. It also seems to already be reported in #1073996. This bug could be closed as a duplicate if you don't want it hanging around. I'll add myself to the CC of the other bug. Thanks for spotting out! Let's close as dup. *** This bug has been marked as a duplicate of bug 1073996 *** |
Created attachment 754552 [details] Strace of pulseaudio strace Hello, after updating to snapshot 20171213 or later, I don't have sound anymore. Rollbacking to a snapshot before that one restores sound. `top` reports high CPU usage for pulseaudio (~50%) and X11 (~95 to 100%). Pulseaudio cannot be killed except with a SIGKILL at which point X11 calms down too. `strace` on the running pulseaudio process seems to indicate that it is in some kind of loop (see attachment). `journalct -t pulseaudio` yields the following: Jan 02 13:51:47 linux-0yez pulseaudio[2620]: [pulseaudio] alsa-mixer.c: Volume element Speaker has 8 channels. That's too much! I can't handle that! Jan 02 13:51:47 linux-0yez pulseaudio[2620]: [pulseaudio] alsa-mixer.c: Volume element Speaker has 8 channels. That's too much! I can't handle that!

Jan 02 13:52:12 linux-0yez pulseaudio[2620]: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez': timed out ":0" is the correct display (`echo $DISPLAY` in konsole also shows ":0"). Manually starting pulseaudio with `/usr/bin/pulseaudio --start --log-target=syslog` after killing it does *not* reproduce the error. The error occurs on two different systems of mine (others don't use oS) with no overlapping hardware so far. Greetings Fabian
