Whenever I'm playing a wmv file that uses wma audio with a samplerate of 16000Hz and below MPlayer freezes after the first audio block. This only happens with ao alsa and only with small samplerates. Oss emulation is fine. It doesn't happen either when I start MPlayer with -ao alsa:device=hw=0.0 so maybe this is a dmix bug after all. I attached a log with some extra debug printfs at the end of the get_delay, get_space and play_normal functions. As you can see get_space always returns 0 even though the audio should have been played already. The test file can be found at http://www1.mplayerhq.hu/~faust3/stapelfahrer_klaus.wmv Any ideas?
