toslink optical connection has intermittent hum
Hi all,
I have an odd problem. I have my pc audio connected to my stereo via the optical out. I am getting an intermittent humming noise (sorta like a ground loop hum but of course that is impossible for optical).
Now, this noise is independent of the volume level I set in windows, BUT if I mute windows audio it stops. It appears connected to google chrome, because if I go into the realtek digital output settings (where you see master volume and the volume for various apps like chrome, etc) and I mute only chrome it goes away. It also goes away on its own for no reason Ii can fathom. It is always the same volume regardless (unless I turn my stereo volume up).
It appears that chrome is outputting a constant low level noise for some unknown reason at unknown times. Does anyone have any explanation/ fixes for this? It is pretty annoying.
Thanks,
Pete
