I didn't want to get into a length description of the problem without first seeing if there were any obvious changes. There are still a few things I can debug. The problem I'm seeing is that when using mplayer to play a video file through the OSS interface, at some point in the movie, the driver will stop telling ALSA that has finished playing a period. It's almost as if ALSA is throttling the driver incorrectly. If I tell mplayer to just play the file through OSS, the problem occurs almost immediately. If I tell mplayer to convert the sample rate from 44100 to 48000 (my driver understands 48000 but not 44100), the problem doesn't always occur, but when it does (about every other time I play the file), it starts to happen about 5 seconds into the file. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
