First of all thank you for your hard work to bring Lineage OS for this phone. I bought a used A5 2017 (dual sim version) last week, and tested with stock ROM, then installed the latest Lineage OS 17.1.
I have only one problem. If I connect a headset to jack connector and use it for Telegram/Duo call, the sound is crackling. I can reproduce the problem: start LOS stock Music app, play some music (the sound is OK), then start Recorder app and record (the sound output is crackling).
It was OK with stock Samsung ROM, and it is OK with LOS + Bluetooth headset.
Has anyone run into the same problem? If yes, then how was it resolved?
