Sorry for replying so late. If I don't specify the audio device manually
 mplayer uses the first (default) audio adapter, that is not supposed to
support that format. The option -format -s24le does not help.

Here is an uncut output of mplayer -v (I just checkedout the last svn):

And, in case it's useful, also of aplay -v:

Is the suggestion of Martijn (i.e. the problem is that s24le and s24_3le
are different, and mplayer does not support s24_3le) good?

Thank you!
