I thought I was literally being hacked! My webcam light comes on and my volume jumps from where I set it to FULL randomly all on their own. Yes, I have pulse audio installed and everything was working fine-n-dandy until I lost the satellite speakers in my 3 +1 setup [satellites and subwoofer] and replaced the satellites with a cheap soundbar.

Now, no matter what I do, I see my webcam turn itself on randomly and I know the volume is set to 100% again. I just wait for the webcam light to go out and lower it to 30% again. Upon boot up, it's at 100% also.

What gives!?!?!
