While looking into a loud buzz while watching a U-Tube video, I updated the audio driver in the device manager. The update was loaded, haven't had the buzz come back....yet.

Prior fix was disconnecting power and battery, reboot, which is hard on the O/S....

Anyways under "other device" I noticed I have an error "!" for base system device. No update works and it is an unknown manufacturer. I have no known issues....is this important or needs to be fixed?
