I was very unsatisfied with the MI TV Stick's audio delay (I made a post about it a couple of months ago). I had high hopes that a system update will fix it. After checking out the new update I was immediately let down. I even recorded a video about the delay that I only have with the Mi TV Stick (and no other devices).
I recorded and slowed down a test video played with the Youtube app. It seems that there is a 200-250ms audio delay which is unacceptable. Can others verify this, too, and maybe let the developers know about it?
Here is my video:
Edit:
In the meantime a friend tested another Android TV device with his LG CX OLED and it has audio delay, too. Might be something general.
Either I don't have the problem on my MI TV stick or I'm not noticing it
