[OnePlus 8 Pro Questions & Answers] jewnersey:
Thanks for replying. I should also mention that system sounds aren't working either- no audio output at all, even from earpiece. I found this post which sounds similar to my experiences with a similar log, as below: "audio_extn_sound_trigger_update_stream_status: invalid input device 0x". They solved their problem: "I think I fixed it, I just switched from one slot to the other. Maybe my firmware was only on one partition or something?"

The phone is currently on 15_O.34_210201: Build number 11.0.4.4.IN11AA. I am in Australia which I believe uses the Chinese version of the device? I tried to flash a different version (EU/Global) to see if it had to do with device related drivers, but I got an "Unknown target O2" error. Model in system says it is IN2020.

System update that is available is IN2025_11_F.13_2130_202211142346 which sends the phone into bootloop OR installs but crashes during setup.

Video when trying to play through speaker plays at ~1/4 speed. I completed a factory reset and then set it up without any account or network. Log is attached which consisted of me turning on the screen, opening YouTube, starting a video, then adjust volume.

I am not going to pretend like I know what I am doing with the logs but here are standout lines pertaining to those processes you mentioned:

Line 89091 and 95938
