My experience is that with multiple sound devices, the wrong one is picked
as the default more often than not. On my machine, I've had to replace the
unversioned links to device 1 rather than the default 0. And set
AUDIODEV to /dev/dsp1 to get GStreamer applications to work. Some things
talk to /dev/mixer as well...
