Like I say, if the codec/driver implement any bypass paths (paths that carry audio from the inputs to the outputs without using the DAC or ADC) then it'll break those - the device will be brought down to standby when there is no playback or record going, which will power the bypass paths down. If that is an issue then documenting it (ideally with printks for users) should cover it for now. If there aren't any bypass paths then it should be fine to leave it as-is. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
