I have two microphones on my computer. One is on my C270 web cam and the other is a headset plugged into my g110 keyboard. The one that was plugged into my g110 was working fine until about 2 or 3 months ago when all the various chat programs I used though the browser for work (hangouts, webex, etc.) stopped recognizing I even had a mic when I used Firefox. The worked correctly when I used Chrome. The audio though my headphones plugged into the same keyboard works fine only the mic is the issue. I recently got a C270 and now when I try to use those programs the popup asking to share my mic has returned, however the only thing that shows up is the C270 mic not the USB one though my keyboard. I do not want to use the C270 mic as it is not very good and picks up to much background noise so I am still having to use chrome any time I need to do audio chat or conferencing for work.
