Upper speaker problem again after the latest update

[Claymann3000]

1. Rog Phone 6 

2. 33.0610.2810.81

3. Not rooted.

4. Very often, every couple of minutes.

5. Every app like YouTube, Tidal.

Guys I hate to tell this, but the problem concerning the upper speaker suddenly losing its volume to about 30% is here again. And what is more frustrating, the restart doesn't help.

More to this, listening with headphones and I suddenly hear sound in mono rather then stereo, for about 10 seconds and then back to normal. It is not headphones themself, checked with other devices.

The factory reset doesn't change a thing.

Guys

If there is no other idea how to help me with the problem, could someone please advice me how to revert back to firmware 33.0610.2810.72 which I consider free of those speaker and bluetooth audio malfunctions? If the problem still exist, then nothing left like sending it under warranty.
