Weird lisp/tin can sound

[PoJ]

I have no idea why those were at stereo repeat

Other persons that have access to your computer?
Someone playing games with you by changing your Voicemeeter settings, while you are in the kitchen?

Seriously, I hope we can close this case here.
Sorry, please it is not my intention to be rude, but your answer was a little bit funny.

Best Regards!

I've prolly put them on that myself, or the noob in me. And you are not rude at all, your help is greatly appreciated.

I watched some YT clips on how to install VM and they did it that way. I'm a total noob with this audio stuff.

Ok, everybody that begins to use something that he has not used before, will make mistakes.
It is natural.
It happens every day.
It happens to you and it happens to me!

It still gives me the weird lisping sound. I removed voicemeeter, not worth my time.
