Redmi Note 8 Pro sound issue.

Hello, yes I have exactly the same problem with the same phone except that my volume goes up by itself and I can’t turn off my phone either.

Hello,

I had the same problem with my Redmi Note 8, and what happened was that when I wanted to lower the volume, it would go up to maximum all of a sudden.
Moreover, it would say "game creation..." when I pressed too long.

I found the issue, and it was dirt; I removed the case and blew on the button to increase the volume, and it worked!

I think in most cases, it's just dirt...
I hope I answered your question and the others'...
Have a good day.

Hello,

I have the same problem as you with my Xiaomi Mi 9T. The volume goes up by itself to the max.

Yes, me! This has been happening to me for a week. Yet, the button is not broken and has not been subjected to any impact. It lowers the volume completely at any moment, during calls, listening to videos or music...

Exactly the same with my Xiaomi Mi 9, I read on another forum that it could be dust behind the buttons.

Personally, it had happened to me once two weeks ago, I let it completely drain its battery and then I waited one day without touching it. It stopped but it's happening again.

Hello, my Xiaomi Redmi Note 8 increases the volume by itself without me touching it.

I had the same issue; I had to remove the soundbar, but I cracked it in the middle (with a knife, I didn't have the proper tools), and I just cleaned the dust that had accumulated, and since then, it hasn't had any problems.

Hello Yes, I have exactly the same problem and I don't know how to solve it.

I have the same problem too.

yes unfortunately and I don't know what to do

Yes, I have the same problem... I don't know what to do...

Hello, I'm experiencing exactly the same issue. Have you resolved this problem? Thank you.
