ROKU Stick Overheating

leadhead

So I just bought the MagniFi Max soundbar and plugged my ROKU stick into it last night. I got a message during our show that the ROKU was overheating, and sure enough it was. I tried an older ROKU stick and while I didn’t get the error, it was also very hot. Same result using the usb power source on the soundbar or the provided wall charger. Anyone else having this problem? The only thing I can think of that we did was accidentally plug the ROKU into the HDMI ARC output for like a minute, the caught it and put it in HDMI 1.
