Strange issues when calling (seems a driver issue)

Help Fairphone 6
1

I’m on the 122 version of the fairphone OS, device is rooted.

When I’m calling our vet, we get a selection menu. When I select the option I need before the message is finished, the app disconnects with ‘server unavailable’, when I select after the message is finished, no issues. (Never had those issues with Lineage)

Also, when using my headphone, sometimes the sound the one hears when I talk is to low. Switching to phone solves this. When I reconnect and call another contact, all is fine. Looks like an intermittant problem.

With installing the unofficial Lineage build I hoped this would be solved, but it doesn’t seem to be an issue with the phone app but with the drivers (as they are used in this build as well) Both the ‘server unavailable’ issue is there as well as the not working mic when using bluetooth earbuds.

Edit: changed the title, as the cause is probably somewhere in the drivers.
