Hi,
I've a bug here: when playing audio via the speakers of a monitor attached to a DisplayPort and I mute the corresponding S/PDIF (i.e. with alsamixer) then the monitor switches off into standby, unmuting the S/PDIF turns the monitor back on. 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
