Since you're not using ESD, this probably isn't your problem:

However, it may be worth checking that you've got all the appropriate SDL
packages installed.

It sounds like it is, though I thought ESD was supposed to fix such problems
and allow multiple programs access to the sound card at once.

Well, my /dev/dsp is a link pointing to /dev/dsp0, and the latter looks like
this:
# ls -l /dev/dsp0
crw-rw---- 1 root audio 14, 3 Apr 1 15:03 /dev/dsp0
but keep in mind I'm using 2.6.5, so if you're on a 2.4 series, your device
files may be quite different (I'm not totally up to speed on those
changes).
I wouldn't suspect device problems, if some applications can use the sound
card, unless those applications are running as root, or frozen-bubble is
running as a non-root, non-you user (not likely).
What happens if you set the environment variable "SDL_AUDIODRIVER" to "esd"
when using ESD? Or does nothing work with ESD?
If all else fails, set the SDL_DEBUG environment variable and start
frozen-bubble from the command line, and paste the output.
