I admit I haven't tried it but I suspect the options wouldn't mean much 
to me and I'd be on a 6 months learning curve googling & RTFMing to 
understand what I need to set up. TBH at the moment I don't understand 
enough (and don't have enough time to put into learning) Linux & related 
stuff to embark on compiling my own version of mplayer.

Looks to me as if your mplayer is using oss for sound output whereas 
mine is trying to use alsa. (My vague understanding is that these are 
two different interfaces between programs and the sound hardware.) Given 
that the package of mplayer (from marillat IIRC) is supposed to be for 
this version of debian and I guess they had it working when they 
packaged it I'm hoping that it's some sort of configuration thing on my 
installation. Maybe there's some dpkg-reconfigure incantation if I knew 
where to look.

FWIW I think there's something wrong with the sound setup on my machine 
because if I'm playing something in realplayer, xmms or audacity and 
something like a terminal tries to generate a sound (e.g. beep) it gets 
held up until xmms (or whatever) takes a break between tracks, and then 
it locks out xmms for a few seconds. The lockout time seems to be set in 
kde control centre's 'Sound & Multimedia'/'Sound System' settings.

I've tried installing ALSA and selecting it in kde control centre but I 
get an 'Informational artsmessage' 'Error while initialising the sound 
driver: device: default can't be opened for playback (No such device)"
