Why is no audio output from my Denon AVR-4311CI Stereo Receiver?

If there is no audio output, check the connections for all devices and speakers. Also, verify that the audio device is powered on, the master volume is adjusted appropriately, and mute mode is off. Ensure a suitable input source and mode are selected, and disconnect any connected headphones, as they disable speaker and PRE OUT connector output.
