I am using Logitech C920 for recording Video and Audio. The Audio quality was great until last week, and I recored 12 videos with stunning audio quality. But for the last couple of videos, the quality of Audio is not that great. I am not sure what has changed in my recording set up. Will windows automatic updates cause such audio quality issues? I tried restarting the machine, plugging the cam in the different USB port, change the distance of the microphone. But nothing helped. 

Did anyone face such issues?
