pulseaudio not usable with fvwm and also KDE
Last modified: 2013-03-18 21:27:14 UTC
After update from 11.4 to 12.3 pulseaudio is crying in the logs: 2013-03-16T18:39:32.828031+01:00 speedy pulseaudio[4493]: [pulseaudio] authkey.c: Failed to open cookie file '/home/werner/.config/pulse/cookie': No such file or directory 2013-03-16T18:39:32.828573+01:00 speedy pulseaudio[4493]: [pulseaudio] authkey.c: Failed to load authorization key '/home/werner/.config/pulse/cookie': No such file or direc2013-03-16T18:39:32.922607+01:00 speedy bluetoothd[4502]: Unable to get on D-Bus 2013-03-16T18:39:32.923024+01:00 speedy pulseaudio[4496]: [pulseaudio] bluetooth-util.c: org.bluez.Manager.GetProperties() failed: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 2 matched rules; type="method_call", sender=":1.8" (uid=1000 pid=4496 comm="/usr/bin/pulseaudio --start --log-target=syslog ") interface="org.bluez.Manager" member="GetProperties" error name="(unset)" requested_reply="0" destination="org.bluez" (uid=0 pid=4502 comm="/usr/sbin/bluetoothd -n ") 2013-03-16T18:39:57.934957+01:00 speedy pulseaudio[4496]: [pulseaudio] bluetooth-util.c: org.bluez.Manager.GetProperties() failed: org.freedesktop.DBus.Error.TimedOut: Action of org.bluez timed out and I'm not able to play anything.

IMHO the HOME of user pulse should be /var/lib/pulse and not /var/lib/pulseaudio
Q: What about setting /usr/bin/pulseaudio setgid audio as the devices are group audio
Even KDE users can not use pulseaudio ... now with chown root:audio /usr/bin/pulseaudio chmod 2755 /usr/bin/pulseaudio it works as it should. Maybe a service daemon pulseaudio running as user pulse which the other pulseaudio clients could use would be an other option.
Please check getfacl /dev/snd/* Here is what I see for all files there: # owner: root # group: audio user::rw- user:sbrabec:rw- group::rw- mask::rw- other::--- ACL permission should be set for the user logged to a local session. It was handled by ConsoleKit in past. I don't know implementation details in 12.3, but I guess that need interaction with polkit.
Created attachment 530254 [details] getfacl /dev/snd/* The output of sudo getfacl /dev/snd/*
Indeed there was no polkit running compare with bnc#809821 and bnc#809807
Permissions in /dev/snd now look correctly. Does it work now if you revert SGID of /usr/bin/pulseaudio and restart pulseaudio daemon (e. g. re-login)? If it works now, it is probably a consequence of with bug 809821 or bug 809807.
Indeed this does work: /home/werner> ll /usr/bin/pulseaudio -rwxr-xr-x 1 root audio 88280 Feb 14 22:19 /usr/bin/pulseaudio /home/werner> grep audio /etc/group audio:x:17:pulse /home/werner> pacmd list-sinks | grep name: name: <alsa_output.pci-0000_00_1b.0.analog-stereo> /home/werner> paplay /usr/share/sounds/alsa/test.wav /home/werner> *** This bug has been marked as a duplicate of bug 809821 ***
