On my work Fedora 10 desktop (upgraded directly from F8) pulseaudio
doesn't run and I don't know how to fix it.  On my home Fedora 10
desktop (upgraded to F9 then F10) pulseaudio runs OK.  As a workaround
I have run "chmod o+rw /dev/snd/*" to allow Audacious audio player as
non-root user access to ALSA kernel audio devices to be able to play
music.  Help troubleshooting pulseaudio appreciated.

How are you starting your desktop? If the sound device is not accessible for
your user, PulseAudio can't use it either, as it also runs as your user.
You need to log in in a way which is recognized by ConsoleKit, which in F10
means GDM or KDM. (In F11, other ways to log in should work.)


I login to the desktop using GDM.

To me Fedora 10 appears to set the permissions of the ALSA sound
devices to read-write for root only and none for all other users. To
allow this to work pulseaudio is a setuid root executable.

However my workaround on my broken work desktop was to allow all users
read-write access to the sound devices, so now pulseaudio can access
the sound device but it still fails to start.
