Audio all messed up

I was fine. Now in meetings my voice gets clipped, it repeats, it cuts out. 

I have been thru every audio setting.

Tried two different camera/mics.

Moved the speakers farther away than ever. They were never an issue before.

I uninstalled and reinstalled.

It is not a background noise issue, there is no other noise.

I toggled thru all the audio settings, trying to see what made a difference.
Nothing did.

I've been using it with no issues up to this point.

Help.
