Tiktok
Something is going on with audio playing in tiktok, which happened for about 2 weeks now, sometimes it plays a sound that makes your speaker sound faulty. Sound that only happens when you play a really loud song for a long time, buzz like sound with a bass.
Tried to play the sound outside tiktok, then it stopped. It also does not happen in all tiktok videos, you need to check if it was caused by tiktok or the content of some video itself. I never had this kind of issue on another app.
