Why is there no sound coming from my Onkyo TX-SR502 Receiver speakers?
- R
  randyjacksonAug 12, 2025
  If no sound is coming from the speakers connected to your Onkyo Receiver, first, ensure the receiver isn't muted. If the MUTING indicator is on, unmute it. Check that all audio connecting plugs are fully inserted and the inputs/outputs of all components are correctly connected. Verify the speaker cables have correct polarity and bare wires are properly in the terminal. Select the correct input on your TV that corresponds to the AV Receiver connection. Also, disconnect any connected headphones. Set the input signal format to Auto, increase the volume, and configure the speaker settings, including specifying connected speakers, distances, and levels. Finally, ensure the source component is outputting digital audio in a compatible format.

  Nicholas ColemanAug 16, 2025
  If the subwoofer connected to your Onkyo Receiver is not working or is very quiet, check the Speaker Configuration to ensure the Subwoofer setting is not set to No. Also, verify that the subwoofer volume is not set to the minimum. If speaker set A is turned off, turn it on, since the subwoofer output doesn't function when only speaker set B is active.

  If the surround speakers connected to your Onkyo Receiver are not working, first, check the listening mode, as some modes do not utilize surround speakers. If the listening mode is correct, try different source material, as some content may not heavily use surround speakers. Ensure that the surround speaker level is not set to minimum. Finally, verify that the Surround setting is properly configured in the Speaker Configuration.
