Hmm, I am using ALSA through dmix and plug plugins so resampling is done by ALSA itself.
Next I wrote that using command aoss mplayer film.avi -ao oss with the
same ALSA config I got perfect A/V sync. In second case I use a library
wrapper which simulates OSS on top of ALSA. So ALSA is used in both
situactions - film is also the same. So in my opinion problem lays on
mplayer's side.
