The mmap support is somewhat broken.  The way dsp_mmap() tries to figure out
which channel to use is wrong, see the comment in sndmmap().  The format
check in dsp_mmap() prevented me from running quake, quake (or other id games)
does a mmap before setting the format.  So it is probably a good idea to
reinitialize the channel to use one of the natural formats instead of returning
a failure.

PS: I've successfully compiled quake on FreeBSD. If people are interested,
    maybe I can make it into a port.
