iPad sound problem

I have an iPad 6th gen (2018 version) with newest iPadOS-version ’iPadOS 16.5.1 (20F75)’ and I have had this problem maybe almost a half an year since I first noticed it. So whenever I go to some games etc. or even try to listen to a ringtone from settings the sounds starts to glitch in a moment and then disappears completely. After that I can’t hear any sounds no matter how low or high my volume is. But if I try to turn up or down the volume the sounds come back for just a second and then disappears again.

I think this problem is someway related to the system or application versions or both, but as I said I’ve been waiting for almost a half an year

so what should I do to fix this VERY annoing bug or when will Apple create a fixing update for any sound issues?

Thanks for any repplies
