Bug Description

If I log out on raring and back in again I get:

Apr 10 09:09:52 lenovo-3000-n100 pulseaudio[14091]: [pulseaudio] socket-server.c: bind(): Address already in use
Apr 10 09:09:52 lenovo-3000-n100 pulseaudio[14091]: [pulseaudio] module.c: Failed to load module "module-esound-protocol-unix" (argument: ""): initialization failed.
Apr 10 09:09:52 lenovo-3000-n100 pulseaudio[14091]: [pulseaudio] main.c: Module load failed.
Apr 10 09:09:52 lenovo-3000-n100 pulseaudio[14091]: [pulseaudio] main.c: Failed to initialize daemon.
Apr 10 09:09:52 lenovo-3000-n100 pulseaudio[14088]: [pulseaudio] main.c: Daemon startup failed.

If you check the process list you find another pulse audio running from the previous login session.

This fault disables the sound controls in the interface.

A work-around is to remove the pulseaudio-esound-compat package, hopefully you don't use any apps that only support esound right?

THe commit 7fad67c46188991c04a42b190349ebb3f4a1756f causes this problem to occur, however the commit is not directly responsible. Rather there is something in our session startup that is not behaving correctly thats causing pulse clients to not find the original pulse daemon. Granted the pulse daemon should really be killed off at logout, and longer term upstart user session jobs will see to that, but for now, we need to find the problem, and at least work around it. Reverting this commit is certainly one option...

David, what do you think?

summary: - pulseaudio fails to die properly on logout
+ A second pulseaudio daemon is spawned after logging out and back in even
+ though one is already running for the user.

This is due to xdg_runtime_dir being deleted on logout. If we then log in again we cannot connect to ourselves ( /run/user/xxx/pulse/native has been deleted), and we're left with stale pulseaudio processes.

Hi Luke,

I've spent today working on a fix, which I have now uploaded to our bzr branch. Since this is last minute, could you help test it? I find it working, if you find it working too without causing some other regressions, feel free to upload it.

Thanks.

Updated the system this morning. After reboot the pulseaudio process takes 100% of one cpu core.
