Headphones vs Headset detection

[jmorris]

evtest shows microphone detection when the headset is inserted but nothing on headphone insertion.

I am not able to reproduce that. Pinephone Community Edition. Mobian running 5.11 kernel:
First two entries are headphones. Last entry a headset.

Code:

Input driver version is 1.0.1
Input device ID: bus 0x0 vendor 0x0 product 0x0 version 0x0
Input device name: "PinePhone Headset Jack"
Supported events:
  Event type 0 (EV_SYN)
  Event type 1 (EV_KEY)
    Event code 114 (KEY_VOLUMEDOWN)
    Event code 115 (KEY_VOLUMEUP)
    Event code 164 (KEY_PLAYPAUSE)
  Event type 5 (EV_SW)
    Event code 2 (SW_HEADPHONE_INSERT) state 0
    Event code 4 (SW_MICROPHONE_INSERT) state 0

That second to last line is the key, I don't see that on PostmarketOS-Phosh.  Thought everybody was running the same basic kernel.  Apparently not.

Was already digging into ALSA's Use Case Manager to add a manual config.  Instead the plan has to be to figure out what is different and get PMOS to pick up that change.  Thanks.
