Can't play audio on multiple X sessions

[beejayzed]

I'm using the fedora 8 setup of pulseaudio here. If I run xinit -- :1 to get a new X session, then run aplay /path/to/sound, it appears to not play. However, if I switch back to :0, I hear the sound playing. So it will only play if I go back to the original X session.

I have this exact same bug.

I use this script to start a game in wine on a different x server, but the sounds plays on the first x server.

#!/bin/sh

GAME_PATH="CCP/EVE/bin/"
GAME_EXE="ExeFile.exe"

xauth add  :1 . `mcookie`

WINE_CMD="pulseaudio & cd $GAME_PATH ; wine $GAME_EXE"
xinit /bin/sh -c "$WINE_CMD" -- :1

I've done some more research and it seems that PulseAudio tries to connect to a PulseAudio server on the current X server, but if that fails, it tries other options, and ends up with the PulseAudio server from the first X session (in this case, and that PulseAudio server only has a sink on the first X server)(from http://www.pulseaudio.org/wiki/FAQ, Question 18). So far for explaining why we get sound on the fist X server.

If I run 'pulseaudio -vvv' I get the following output:

It seems that the detection of the sound devices is going wrong. Running it as sudo, I get the exact same output, so it's not a permission problem.

I'm at a loss as to why it won't detect the sound card correctly, is there some way to get more logging from module-hal-detect?

PA is not intended to be run as root.

HAL+ConsoleKit? by default make sure that only the active session on the seat can access the audio hardware. This is intended behaviour.

Closing as invalid.
