HDMI jack detection broken after suspend/resume
After suspend/resume, the HDMI port does not show up, but it can still be used (if you use e g pavucontrol to select it). Sometimes, doing seemingly unrelated things, such as running the alsa-info script, restarting PulseAudio, etc can make it show up again.
Found on both NVidia and Intel hardware.
Which kernels should we consider backporting to?
* upstream stable
