  Several factors can cause a lack of sound from your Onkyo Receiver. First, ensure that the receiver is not muted. If the MUTING indicator is on, unmute the receiver. Check the audio connections to confirm that all plugs are fully inserted. Verify the speaker cables are correctly connected, paying attention to polarity. Select the correct input source on your TV to match the receiver's connection. Remove any connected headphones. Ensure the input signal format is set to Auto, not PCM or DTS. Adjust the volume to an audible level. Configure the speakers correctly, specifying which ones are connected, their distances, and individual levels. Confirm that the source component is outputting digital audio and that a compatible digital audio format is selected on the source component.

  If the surround speakers on your Onkyo receiver aren't working, it could be due to a few reasons.

Also, remember that surround speaker output depends on the source material, so ensure you're using a source that supports surround sound. Check that the level of the surround speakers is not set to minimum and adjust it if necessary.
