All data transfer are 8 Long Word brust transfers This mean that the driver may need to limit the period bytes to be multiple of 8 Long Word since interrupt occur when a cache fill/transfer between the PCI memory and the internal memory. snd_pcm_hw_constraint_step(runtime, 0, SNDRV_PCM_HW_PARAM_PERIOD_BYTES, 32); and you may also need to set "rewind_safeguard" in PA too. http://git.0pointer.de/?p=pulseaudio.git;a=commit;h=4df443bbe682055a41e7c2248877dcc7682a69b8 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
