alsa-project/alsa-ucm-conf issue #336 was opened from jenneron:
The problem is that both headphones and mic use `JackControl "Headset Jack"` When there are headphones without mic connected it switches to external mic which is not present.
In kernel there appears to be only one switch https://github.com/torvalds/linux/blob/3c8b5861850c734add65233e538d4a8c2dff9... responsible for handling both headphone and microphone. So, how is userspace supposed to distinguish connection of headset and headphones without mic?
