Question about RCA RS2640 CD Shelf System
Of course it will stop buzzing when you mute the speakers. From the limited description, it could be anything from a power supply to loose wires in the system between the speaker leads and the motherboard. Best bet is to take it in to a technician and get a pro's answer. If he wants to charge more than what it's worth to you, get a new one.

I had the same problem with mine and the fix for it was to replace Q401 transistor on the main board. I used a NTE382
replacement and it has worked fine ever since.
Hope this helps
