Ok, great. Meanwhile, I also did some investigations (I couldn't resist ;-)
and came up with the following (good old printf debugging..)

The error occurs around line 439 of vchan.c, and goes away as soon as
I replace AFMT_S16_LE with AFMT_U16_LE. Of course, this does not solve
my problem, since mplayer also mumbles something about S16_LE. I'm not
too familiar with audio formats, but I guess it is something about
16 bits and signed integers...

                if (!err)
                        err = chn_reset(parent, AFMT_STEREO | AFMT_S16_LE);

Hope this helps you,
