Why is no sound produced from surround back speaker on my Denon AVR-4311CI?

Check if “Amp Assign” is set appropriately to output audio from the surround back speakers. Set “Speaker Config.” – “Surround Back” on the menu to something other than “None”. Also, set “Surround Parameters” – “Surround Back” on the menu to something other than “OFF”. Ensure the surround mode is not set to “STEREO”.
