I think it's reasonable for gstreamer0.10-alsa to use the default
device.  But perhaps it should be checking the capabilities of it
somehow... not sure.  I'll leave the bug on gstreamer for now -
alsa-base seems to have loads of bugs about this already, e.g. #586648
(marked 'wontfix' with the advice to read

I've had alsa order my pcspkr driver first on some machines.  I think
one workaround is to edit /etc/modprobe.d/alsa-base-blacklist.conf to
blacklist the driver.  I also seem to have a file
/etc/modprobe.d/sound.conf that I created at some point to get the
right ordering.
