Try connecting a different pair of speakers. Make sure no headphones are connected to the A/V receiver. Try changing the TV+AMP setting on the receiver to AMP. Try setting the A/V receiver to a different surround sound mode. Check to see if the A/V receiver is set to a surround sound mode.
Ensure the speaker setting matches the type of speakers connected. IMPORTANT: Some Sony receivers have a MicroSP setting in the speaker setup which will cause low audio level when not using Micro speakers.
Run the test tone function (if applicable for your model of A/V receiver). Sony® Elevated Standard (ES) A/V receivers are not designed to allow HDMI audio to be assigned to other input names. NOTE: If the audio problem is only with the HDMI® inputs, make sure the A/V receiver is set to HDMI input and that HDMI is not assigned. Check each input function, including AM and FM, to verify you are not able to get audio through any of the inputs. Verify that the A/V receiver is not set to MUTE. If the speakers are connected to the A speaker connections on the rear of the A/V receiver, then the A/B speaker selector must be set to the A position. IMPORTANT: Make sure that the A/B speaker selector is set to the appropriate position. Verify that the speakers are properly connected to the A/V receiver. NOTE: Because each of these steps represents a possible solution to this issue, check for sound after completing each step. #PIONEER IVIDEO MANUALS#
