F fixit7 Member May 10, 2019 #1 A humming started in my speakers. It's intermittent. I use a Logitech external speaker system. If I turn it's volume down, the humming volume goes down. If I unplug/plug its power source the humming goes away for a while. Any ideas as to the source?

Try a different audio source, make sure it is the speakers. Hum usually comes from the power supply - if it sounds like a low vocal range, it is likely a power supply filtering capacitor (common). If it is a very low (60 or 50Hz, then it could be a diode but this is rare).
