Tanu, I do have the mount point: /dev/shm on /dev/shm type tmpfs (rw) My /dev/shm has: -r-------- 1 jduda jduda 2097176 2008-04-21 08:31 pulse-shm-3230492922 -r-------- 1 jduda jduda 2097176 2008-04-21 08:30 pulse-shm-4012357765 Each new audio attempt creates a new enter in /dev/shm, so, changing permissions has no affect. Using the disable-shm in daemon.conf didn't have any affect, I get the same error messages. I also tried --disable-shm=1 on the command line when launching pulse. 3302 ? S<sl 0:00 /usr/bin/pulseaudio --log-target=syslog -D --disable-shm=1 pstream.c: Recieved SHM frame on a socket where SHM is disabled. Thanks for the feedback. Very strange, I don't know what I could have done, but I broke something.
