This article provides information and steps to help troubleshoot no sound from your source device (Blu-ray Disc™ player, set-top box, etc.) when connected to your TV with an HDMI cable.
Perform each step only as needed to resolve the issue. Steps and information for your device may vary, if you require model-specific information, refer to the
manuals
for your products.
These steps provide easy solutions to common issues that occasionally occur. Check if the issue is resolved after each step is performed.
Try increasing the volume of your TV, set-top box (cable box, satellite, etc.), or sound system connected to your TV.
Make sure the TV isn't muted. Check your TV remote for a MUTE button. Pressing the MUTE button will toggle the mute function on and off. Note: When using a set-top box or sound system connected to your TV with a mute function, ensure this device is also not muted.
Try turning off your TV, any set-top box device (cable box, satellite, etc.), and sound system if connected to your TV, and then turn them back on.
Make sure you don't have headphones or any other devices connected to the headphone jack of your device.
For cable and satellite boxes, try switching to a different channel. An issue can occur with the broadcast of certain channels.
Disconnect and then reconnect HDMI cable connections to both the source device (set-top box, Blu-ray Disc™ player, etc.) and the TV. If the cable is not making a good connection, you could lose sound.
Performing a power restart or reset of your TV or connected devices often resolves an occasional issue.
Power restart or reset your TV:
You may be able to perform a power restart of your TV using the remote control or a TV menu option (depending on the model), otherwise perform a power reset.
Turn off the TV. Note: For a projection TV that uses an internal lamp, wait 5 minutes after turning off the TV to allow the lamp to cool before continuing.
Unplug the TV power cord from the electrical outlet and leave it unplugged for at least 60 seconds.
Plug the TV power cord back in and turn it on.
Power reset your set-top box (cable box, satellite, etc.) or sound system:
Turn off your set-top box or sound system.
Unplug the power cord for the device from the electrical outlet and leave it unplugged for at least 60 seconds.
Plug the power cord back in and turn it on.
Make sure your TV is set to the correct input to receive the signal from the source device. If you lose both audio and video, you may have the wrong input selected. Press the INPUT or Source button on your TV remote to toggle through your options.
Try connecting your HDMI cable to a different port on your TV, making sure to switch the input selection of your TV to match.
Check the HDMI signal format in the TV menu settings, if it's set to Enhanced, change it to Standard.
On the supplied remote control, press the (Quick Settings) or HOME button (depending on the model).
Select Settings.
The next steps will vary depending on your TV menu options:
Select Watching TV → External Inputs → HDMI signal format → select the appropriate HDMI 1 - 4 → Standard format.
Select External Inputs → HDMI signal format → select the appropriate HDMI 1 - 4 → Standard format.
Note: The HDMI signal format setting is specific for each HDMI port. This means that you may need to change the settings for each HDMI port to which a device is connected.
You may need to change the audio output settings on your source device. Try setting the audio output of your source device to PCM or 2-channel audio instead of Dolby Digital® or DTS sound.
Note: These are general suggestions, for specific steps and settings for your device, check your device manual or the manufacturer for assistance.
If you're using a set-top or cable box:
Make sure the volume is turned up. You also may need to go into the set-top box menu and select HDMI in the Audio Settings or Audio Coding section to pass the audio to the TV.
Earlier versions of set-top box firmware didn't properly handle automatic HDMI connections. You may need an update to your set-top box firmware, or a newer set-top box from your service provider.
If possible, try connecting your source device to a different TV.
Note: This step determines if the issue is with the source device. If you have sound with another TV, continue troubleshooting to diagnose the original TV. If you don't have sound, there may be an issue with your cable or the source device.
If you haven't done so already, try replacing the HDMI cable.
