There is an egregious bug in gmplayer, where it blithely tries to open
ALSA devices (hw:x,x) using OSS device names (/dev/mixer).  I have been
meaning to file a bug report but didn't have the bandwidth, but now
people are reporting this as an ALSA bug.  To make matters worse, the
problem only occurs in gmplayer, and that regular mplayer works fine.

Is this fixed in a more recent release?
