Speaker near the front camera and left bottom speaker are not working

Hello, today I realized that the speaker near the front camera and the left bottom speaker are not working. Only right bottom is working. A few days ago all speakers were working correctly, i hear everything in stereo. I checked my settings and mono sound is off so stereo is still on. I have iPhone 11 and iOS 16.1.1.

Edit: Speaker near front camera is working correctly during calls but not when I watching youtube, netflix, etc…

What can I do with that?
