Hi!

Wow, some crazy audiorate conversions going on there. The solutions I
can think of are: First and most important, you're missing
audiorate=32000 in the -tv options. Second try again with
alsa:adevice=hw.2,0 instead of adevice=/dev/dsp2. Third, add
-srate=48000 to the mplayer options.
Also, I would seriously recommend you to switch to mplayer cvs, that
alone could fix the problems, as mplayer-1.0pre7 is very old.

Regards,
Uros
