While in a call, all other sounds are really low.

So I get that this is not a bug, but while I'm in a Facetime call, the volume of everything else but the call is reduced.

I get that this may be good, but not in my case. I use it to chat with my friends while I play, and I can barely hear the sound of the game.

I looked and looked for this setting but I couldn't find anything, and also didn't find any similar questions.
