Gstreamer players fail when other backends in use

[Matthew Vermeulen]

When trying to use a gstreamer based player while another non-gstreamer based application is using the sound card nothing plays and this leads to the following error in the syslog:
module-alsa-sink.c: Error opening PCM device front:0: Device or resource busy

This is a big problem because I usually have me-tv (xine backend) start loaded in the tray, and then no gstreamer based players (elisa being my favourite) will play. Firefox will sometimes cause gstreamer based apps to fail in this way. Two gstreamer based apps (I tried totem-gstreamer and elisa) will work fine together. I tried:

Xine and Totem-gstreamer
Me-tv and elisa
Me-tv and totem-gstreamer
Mplayer and totem-gstreamer
Mplayer and elisa
Totem-xine and totem-gstreamer
Firefox (and youtube) and totem-gstreamer

In all of these cases, the gstreamer based app will fail to play with the above error in the syslog
