Previous solution didn't work with tsched=0, and used tsched_watermark for guardband, which isn't linked to hardware and could become really high if underflows occurred. But the rewind issue is not limiting to (PCIE) HDaudio since all PCI sound cards would have the same problem ? i.e. snd_pcm_rewindable() return wrong value _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
