IMPORTANT: If model-specific information is needed to complete any of these steps, refer to the operating instructions supplied with the product. Manuals are posted on your model support page.
NOTE: Because each of these steps represents a possible solution to this issue, check for sound after completing each step.
- Verify that the speakers are properly connected to the A/V receiver.
IMPORTANT: Make sure that the A/B speaker selector is set to the appropriate position. 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.
- Verify that the A/V receiver is not set to MUTE.
- Check each input function, including AM and FM, to verify you are not able to get audio through any of the inputs.
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. Sony® Elevated Standard (ES) A/V receivers are not designed to allow HDMI audio to be assigned to other input names.
- Run the test tone function (if applicable for your model of A/V receiver).
IMPORTANT: Some Sony receivers have a MicroSP setting in the speaker setup which will cause low audio level when not using Micro speakers. Ensure the speaker setting matches the type of speakers connected.
- Check to see if the A/V receiver is set to a surround sound mode.
- Try setting the A/V receiver to a different surround sound mode.
- Try changing the TV+AMP setting on the receiver to AMP.
- Attempt to increase the volume level.
- Make sure no headphones are connected to the A/V receiver.
- Replace the speaker wires.
- Try connecting a different pair of speakers.
- Low volume may also be a result of another component connected to one of the input sources, such as a Set-top Box (STB) or television.
- Check the connection between your source and the A/V receiver to make sure they are securely connected.
- Try a different input jack to eliminate any issues with the current jack that is being used.
NOTE: If the audio is being sent from a television or STB to the A/V receiver, it may be necessary to disable the internal speakers of the input source or set the audio output of a TV to FIXED or VARIABLE. If the audio output of a TV is set to VARIABLE, then you will need to increase the volume level of the TV.
- Switch to a different source, such as a CD player, to verify whether the volume is low on all sources or just the one that you are using.
IMPORTANT: If the volume level sounds fine on all other input sources or when playing the A/V system separately, contact the manufacturer of the input source with low volume for further assistance.
If the issue is still unresolved, service may be required. Begin the procedure to send your Sony product into a Sony facility to be repaired.
