gmplayer sets mixer_device from gtkAOOSSMixer even if alsa is used.
The problem was hidden until: 
http://mplayerhq.hu/pipermail/mplayer-dev-eng/2004-June/026951.html

A further gmplayer enhancement would to be able to configure the "alsa" 
audio driver from the preferences in a similar way to the "oss" driver.
Additionaly, amixer "simple mixer controls" or "regular controls" 
command-line syntax would be a nice standard to follow for both mplayer 
and gmplayer.
