Speakers Buzzing on Shore Power

[Chappy133]

When I am plugged into a 110VT power source and using the Jensen Radio head for sound (Bluetooth, USB & TV) I get static through the speakers.  When using 12VT only there is no static.  Any suggestions on how to stop this?  The converter/ inverter must be creating this situation.

I wonder if the AC system is getting properly grounded through the power supply. Check the cord, plugs, receptacles, and the wire where the converter AC side has the ground attached.

Will take a look.
