If you have a device connected to the 3.5mm jack on the TV, the sound may not be out from both TV speakers and the device simultaneously, depending on your model. You may refer to How to get sound from headphones and the Bravia TV speakers at the same time article for more details.
Follow this procedure if the TV speakers don't produce sound or have low volume. Check the TV speakers after each step.
- Make sure TV speakers are selected in the audio settings of your TV. Refer to your TV manuals for model-specific information.
- Increase the volume of the TV.
- Make sure the MUTE option of the TV isn't enabled.
- Disconnect headphones or any other device connected to the headphone jack on the TV.
- A power reset or restart of the TV is recommended step and may resolve the sound issue.
- Run the Problem diagnosis for Picture/Sound symptoms.
- If the TV is connected to a set-top box (cable, satellite, etc,) with its own volume control, increase the volume of the set-top box.
- If the set-top box is connected using an Audio/Video (A/V) connection, make sure the A/V cables are securely connected to the appropriate video input on the TV.
- If analog broadcasts are used, perform analog broadcast tuning.
- If audio is heard from the analog broadcasts, the TV speakers are working properly. Check the other input sources or playback content for sound issues.
- If no audio can be heard, proceed to the next step.
- Verify that the MTS settings of the TV are set to MAIN or STEREO.
- If the source device doesn't transmit a stereo signal, sound may only come out of one speaker on the TV, and the volume will sound low. In this case, adjust or replace the source device.
- If the TV has a Simulated effect in the Audio or Sound menu, turn it OFF.
- If the TV has a Volume Offset setting in the menu, increase it to the maximum value.
- Check that the TV speakers aren't set as the Center speaker.
- Some TVs allow the TV speakers to act as the center channel speaker when using a multi-channel receiver.
- Verify the speakers are set to ON in the TV menu.
- If the TV has audio output jacks connected to a stereo system, then the speakers on the TV may be turned off. Some TVs require the internal speakers or the center speaker setting to be off before audio can be sent out to a stereo receiver via the audio out jacks.
- If the TV has Headphone/Audio Out settings in the Audio or Sound menu, set it to Audio Out.
- Make sure all A/V cable connections are correctly connected to the TV.
- Test the TV using another source like a VCR, DVD player, or Blu-ray Disc™ player.
- Check the software version of the TV.
