MPlayer is using whatever sound device it's configured to use,
probably whichever one is /dev/dsp unless you reconfigured it. There's
no way it should be confusing stuff about multiple soundcards.

BTW, do you have aop resample stuff in your mplayer config? If so,
remove it! That code is old and doesn't seem to work well with the
automatic resampling in the new libaf layer.

BTW2, if you still have problems post proper logs and a full bug
report.
