- Only the Mint installation refuses to believe the headset plugged into the 2.5mm audio plug on the Lenovo IdeaPad 5 Pro has a mic
- Mint also won't *play* audio through unless I unplug and re-plug the headset cable -- I think this is because I mute the "Speakers" device to avoid getting audio through *both* speaker and headset
- The above behavior only happens in Mint, so I'm thinking there may be some unaddressed OS-level issues pertaining to 'pluggable' devices?
Sound settings show one input device: Digital Microphone Family 17h (Models 10h-1fh) HD Audio Controller
As mentioned, the mic is detected and un-muted when inserted or detected in all Ubuntu and Windows installations. Mint is not finding the headset mic and not playing through the headset until removing and re-inserting the headphone 2.5 mm plug.
