Question about Onkyo TX-DS989 Receiver
'Buzzing' is not a good thing; it implies that filtration of the DC used by the output section is not as it should be.
Power supplies that are mildly overloaded can cause this or an abnormal current drain from one (or more) channels.
The odd problem with the back speakers does sound like a setup problem rather than a circuit failure.
