When my TV is off, the surround sound system will turn on and sporadically make loud buzzing noises. This is not a constant noise, and when the TV is on everything works great. The central unit and TV are connected to the same surge protector, and there are no major power cables near the data cables. I am using eARC, and when I unplug the HDMI cable the buzzing issue stops.

Are there any settings on the TV I should look into?

I appreciate any tips to help. Thank you!
