As I thought, it made no difference. I don't know if the problem is in
mplayer or anywhere else, all I know is that the snapshot from 20090731
works, and current does not.

It takes oss by default, only music and sound no voices (probably it mess
up 5.1, that's why). Adding -ao alsa it works, but same problem than
before.

>> -channels 6 -ao oss

Channels messed up with oss, no voices only music and effects, so I don't
know whether it syncs or not.

So, to sum up, same problem always with alsa. With oss I can't hear the
voices, only music and sounds, so I really don't know if they are sync'ed
or not. I did a pristine compilation, with svn co, ./configure, make,
nothing strange, no crazy CFLAGS or anything else.
