Headphone is ignored when plugged during voip call

[symphorien]

Describe the bug
If headphones are connected during a voip call, elements show the output selector as if headset is was chosen but it is still ouputing sound by the loudspeaker.

To Reproduce
Steps to reproduce the behavior:

1. Unplug the headset
2. Accept a voip call
3. The loudspeaker is used
4. Plug the headset

Expected behavior
The headset is used

Actual behavior
The loudspeaker is still used.
The sound output select displays (wrongly) that it is using the headset.

Same behavior with Element 1.0.9 (F-droid), olm 3.1.2 with Lineageos 17.1 (Android 10 without gapps)

Perhaps linked to #2195?

Is it ignored when plugging in, but can you switch to it manually?
Maybe it's ignored because it isn't even recognised by the app (#1685).

I haven't been able to manually switch to it.

When I plug the headset, the app displays it is using the headset, but in reality it uses the loudspeaker. It offers me to switch to the loudspeaker, but pressing the button has no effect.

I tried with 1.0.11 [40100110] (F-dffdcfe1) from f-droid

I'm going to close this issue for now as we can't reproduce it in a community testing session. Please comment with @kittykat if you can reproduce it in v1.3.8 (coming out next week) and I will re-open the issue
