[MPlayer-users] mplayer acting very slow with -mixer-channel, gmplayer is even worse

[RC]

Have you tried some of the parameters you can pass to -ao alsa.  eg "-ao
alsa:mmap:noblock:device=hw=0.7".  It's best to try each one
individually, of course.

Then there's the other audio options...  Have you tried with "-autosync
30", "-mc 0", "-mc 1", "-mc 10"?  Do they help at all?
