If there is no sound from the surround back speaker, verify the following: Ensure the surround speaker cable is properly connected. Note that if STEREO has been selected for Surround mode, no sound will be output from the surround speaker. The surround back channel is only active in THX surround EX mode, so set the receiver to THX Surround EX mode.
