Hi folks,

Playing videos via mplayer I've got a problem: The Alsa-oss
emulation (mplayer -ao oss) seems to work, but for pure Alsa
(mplayer -ao alsa) the sound seems to be played too fast. And
I get a stream of error messages on the terminal saying

alsa-play: write error: Broken pipe0.000 1/ 1 ??% ??% ??,?% 0 0
alsa-play: trying to reset soundcard
alsa-play: write error: Broken pipe0.022 4/ 4 ??% ??% ??,?% 2 0

Sounds like an mplayer bug. If you play a .wav file with "aplay
file.wav" does it play at normal speed?
