I've already done that method and it's not helpful either way

Same here

[Tokyooo]

Now I'm deciding whether im gonna factory reset this or do nothing. God this is so frustrating

[Tokyooo]

I run a diagnostic test here at samsung member apps and it says that my voice and as well as sounds are cannot be test because it is being used by other app and i don't know what is that app

[JezaM]

It asks me to "close the other app" but there are no other apps open

[Tokyooo]

Same

Got it. I went to Safe Mode, tested some mp3 files audio works there. I returned to the "normal mode" and it's now working for me.

I've done that yesterday but few minutes later after i returned to normal mode the sound disappeared again
