I don't get any more underrun/overrun messages, but the application doesn't know that something's failed. With mplayer, I see this message: alsa-lib: pcm_hw.c:405:(snd_pcm_hw_hwsync) SNDRV_PCM_IOCTL_HWSYNC failed: Broken pipe And then mplayer hangs with the status bar here: A: 0.0 (00.0) of 249.0 (04:09.0) ??,?% $<50> aplay just hangs. I also tried adding this code to my _pointer function: snd_pcm_stream_lock_irqsave(substream, flags); if (snd_pcm_running(substream)) snd_pcm_stop(substream, SNDRV_PCM_STATE_XRUN); snd_pcm_stream_unlock_irqrestore(substream, flags); but it didn't make any difference. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
