IMPORTANT: If model-specific information is needed to complete any of these steps, refer to the operating instructions supplied with the product.
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.
