I realize this is a year after your post. I am very frustrated. My voice can be heard but not my guitar. This happens on Skype and Zoom. I have turned off noise suppression. Still has the problem. Nothing like this happened on Windows 10. Now that I have Windows 11...... It's driving me nuts. Did you find a solution?
-This is what J Hioe posted. Great link. Will save you time and frustration.
Hi,
Thanks so much to all who have shared on this post.
It greatly helped me and my community (the piano sound had been suppressed on a Windows 11, HP Envy) .
I created a resource summarising the workarounds listed on this forum for my community - feel free to share if it's helpful.
Special thanks to Lenka, Erop, Paul, Robyn, Dorset, AYMAIA and Robbie.
