Actually the problem happens also with plain PCM rendered on the iec958 device.There's no way to use the IEC switch. So why do we have an S/PDIF switch in the first place? If it cannot be used when you sent IEC-formatted data (be that PCM or AC3-formatted data), then why bother? Allowing for mute doesn't have any impact on functionality, and it prevents the user from muting with alsamixer or a gui. I find this silly, or I am missing something. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
