I am really sorry for replying late
@Gustav_ASUS . I just didn't open the forums. Sadly my phone screen broke from the inside without any dropping or any rough handling and now I am sending it for repair, so I can't really film a video.
But the issue was definitely there, I can confirm. I had the latest update, and the audio delay is too much to neglect. It wasn't there before I updated to Android 10.
