  Misty RiceSep 4, 2025
  If the 5.1 Channel indicator doesn't light when playing a Dolby Digital / DTS source on your Pioneer Receiver, it means that the Dolby Digital / DTS source is not 5 channels. There is no problem with the receiver, but if you want 5 channel sound you must play a 5 channel source.
