Help with Shairport - Pulseaudio vs ALSA

Hello.

I'm having problems with the shairport-plugin in XBMC (running Ubuntu 10.10)
The script starts, and shaiport is visible on my iPhone.
The problem comes when i try to play a song.
(BTW: AirPlay-plugin is working great for video+pictures)

Starting plugin:

Quote:root@xbmc:/home/xbmc/albertz-shairport# perl shairport.pl
Established under name 'B5DA9C11F9D3@ShairPort 5197 on xbmc'

Playing a song:

Quote:ERROR: Failed to load plugin /usr/lib/ao/plugins-4/libesd.so => dlopen() failed
ALSA lib pcm_dmix.c:1018snd_pcm_dmix_open) unable to open slave
ao_alsa ERROR: Unable to open ALSA device 'default' for playback => Device or resource busy

Can somebody please help me with this?
Just let me know if you need more info.

Best Regards,
