Speaking of buzzing, when I got my MBr last month I noticed when going through some of the menus that when I adjusted the backbox GI brightness to anything other than max I would get this hum/buzzing sound out of the speakers. The tone and volume of the buzz would change depending on the brightness amount. At the time I tried looking around to see if anyone else had this issue on a MBr but didn't find anything. It hasn't been much of a problem since I just run the backbox GI brightness at 100% and it's fine.
Today though I hooked up an under cabinet lighting kit from Mezel Mods which is powered off the 12v of the solenoid driver board and it causes this hum/buzzing as well. The 2 strips are RGB and if I set them to a color where any of the 3 RGB diodes are set at to anything other than 100% or off the hum/buzzing occurs.
What could be causing this and is there something I can do to address it?
I also noticed when I got this machine the volume range on it is pretty loud. Like volume level 2 is good, anything above that it gets really loud so I wondered if that might have something to do with this as well.
