[MPlayer-users] ALSA output not working

[David S. Geirsson]

Hi. First off, I'm not subscribed to the mailing list at the moment, so
it would be very good if I be CC'd on any replies.

I just set up ALSA on my laptop, and of course, started by configuring
mplayer to use it. However, whenever I try to play anything in mplayer
with ao=alsa9, I get the following output:

==========================================================================

mplayer works fine if I use ao=oss, using ALSA's OSS emulation - but I'd
much rather prefer running it natively. All other alsa-based apps I've
tried seem to work fine (alsaplayer, aplay and xmms). I've tried files
of both 44.1KHz and 48KHz.

Also, from aplay output:
rate         : 44100
exact rate   : 44100 (44100/1)

So it would appear that the card does indeed go into the exact mode (so
it shouldn't be a problem of the card not supporting the frequency
mplayer wants).

Does anyone have any ideas on what might be causing this?
