Question / Help I could really use some help here, cam sound problems

Hi, so I've posted about this problem before but sadly no one has been able to help me with my problem.
I can stream fine, that is no problem whatsoever with the sound, but when I try to put a facecam in the sound get all weird, to me it kind of sound like an old shitty blown out speaker, but I know that's not the problem, cuz then it would always sound like that.
Also the FPS seem to be pretty bad for some reason when I have the cam on, frame drops and lags.

I streamed a little video "showing" the problem, first with the cam on so you hear it, then a bit later I turn it off so you can see or hear that it's all good after that.

You can start the video at about 2:20 min and you'll get an instant impression, I would really like to know what's wrong, I love OBS and the streaming is so good, but this is a real problem for me.
