[OnePlus 8 Pro Questions & Answers] jewnersey:
I bought a cheap OP8P that was stuck in bootloop and recovered it (MSM tool to reflash A11, then local update to A13). The phone is working fine, but I there is no sound output. This applies to calls and all videos/music. NewPipe spits this error out when I try to play a video:

I have tried reinstalling the update but it didn't change anything.
