[MPlayer-dev-eng] [PATCH 0/5] various enhancements and bugfixes for the ALSA driver

[Jan Knutar]

I'm hitting this assertion with the new alsa patch. It happens immediately
at startup.

mplayer: pcm.c:1054: __snd_pcm_forward: Assertion `frames > 0' failed.

Program received signal SIGABRT, Aborted.

It's not very reproducable for me. It happened constantly with one particular
file, then I did a killall -9 mplayer (there seemed to be alot of mplayer processes
all of the sudden), and after that it magically worked again :/

I'm not sure if this is actually worse from earlier ao_alsa, I seem to remember
that sounds simply went choppy if there were mplayer processes left behind.
