no other-sound when switching user

Binary package hint: mpd

Maybe it's more a pulseaudio bug.

With mpd configured to use pulseaudio, if I switch user when mpd is playing, mpd will keep on playing (this is the right behavior), but the new user won't be able to play any other sound.
When using the GUI to configure sound, it has no sound device and a dummy output.

Everything works fine if mpd is stopped before changing user.

Both users belongs to audio, pulse, pulse-access groups (as well as mpd user).

I think there is a philosophical problem between mpd and pulseaudio. How can a systemwide mpd use a user pulseaudio server without having any troubles at all ??? Two solution come in mind:
* Configure pulseaudio systemwide, which is definitely not recommended by its devs.
* Configure mpd to be a per user instance.
As pulseaudio is now the default in any ubuntu installation, I think mpd should be configured to be a user service. (see http://gmpc.wikia.com/wiki/MPD_INSTALL_USER_SERVICE_UBUNTU for example), and configured by default to use pulseaudio.

Maybe this is not the good place to discuss this... but what would be the good place ?

mpd DOES run per-user. If reporter's experience is anything like my own, what's actually happening is mpd is trying and failing to setup pulse audio and falling back to alsa. this prevents other users with pulseaudio from accessing the soundcard.

[johnnynyquist (johnnynyquist)]

my bad. mpd is running as a dedicated user, not as the login user.

After disabling/stopping the system-wide mpd instance, a user mpd will be started on login provided an .mpdconf can be found
