Hi I am tesing my alsa driver for an arm based board. aplay works well when it is used in blocking mode, but I see underruns when I switch to non-blocking mode. What could be the reason? I have tried to remove all latencies in driver by using minimal locking etc, but it doesn't seem to make any difference. Also, the audio quality degenerates gradually in non-blocking mode. -Pharaoh. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
