When muting the S/PDIF while no audio is playing everything is fine. There's no audio daemon running and my ~/.asoundrc contains only: pcm.!default { type hw card 0 device 3 } I've already filed a fdo bug report (drm/intel) for this as I thought it might be related to it: Bug 75729 - [hsw dp audio] Muting S/PDIF turns off DP https://bugs.freedesktop.org/show_bug.cgi?id=75729 Attached to this bug is a `alsa-info.log` too. As stated in the bug report it's not a showstopper for me, but obviously something seems to go wrong and maybe someone has an idea. Thanks, Daniel Martin
