All of a sudden I have a pretty pronounced 60hz hum in my
Squeezebox. It goes away when I unplug it from the wall.
Any suggestions? Thanks!

Worked fine for about 6 weeks.

Assuming you are in a country with 60Hz power, its a ground loop.
If you are in England, and have a 60Hz hum in the land of 50hz power,
then I don't know.

Something changed. Unplug all your stuff, plug things back in one at a
time. See what causes it. Change that thing.

It is best to use a star powering scheme: run all your audio gear,
amps, squeezebox, etc off the same circuit. Get a power strip and plug
them all in.

In the US, do not just cut off the ground pin (third, round connection
on almost all power plugs). It is dangerous and against the Electrical Code.

Report back after you'd done this.

My Christmas Tree lights did the same for mine. I'm looking forward to composting the tree.

Wins the award as the most novel solution to a ground loop so far this year :-)
