How to Fix Hisense TV volume not working?

  • Method 1: Increase Volume

There is a chance that the volume of the media you are watching is low. Try increasing the volume of your TV.

If you are using a set-top box with volume controls, try increasing the volume of the set-top box.

There is also the possibility that the channel you are viewing has low volume. This issue can be rectified by contacting the service provider.

If the set-top box is connected using an Audio/Video (A/V) cable, make sure the A/V cables are connected properly to the appropriate audio input port on the TV.

  • Method 2: Headphones are connected

Make sure there is not a pair of Bluetooth headphones connected to the TV. Make sure no headphones are connected to the TV also by the audio output jack.

  • Method 3: Change output settings

In case of an update or something else, the output settings may have changed and caused the audio to not come out of TV speakers.

Check the speakers and audio output settings on the TV. Ensure TV Speakers are selected in the options.

  • Method 4: Unmute the TV

Make sure that your TV audio has not been muted. In this case, unmute your TV.

  • Method 5: Check the analogue broadcast

There will be analogue broadcasts available, perform analog broadcast tuning on the TV and check if there is noise.

If there is noise, that is sound coming out from the TV, check for other causes such as apps with no sound or the playback content that has no audio.

On the other hand, if there is no noise, the sound may not be coming out due to an issue inside the TV.

  • Method 6: Change MTS settings

If your Hisense TV has an MTS setting in the audio menu, set it to MAIN or STEREO.

  • Method 7: Replace source device of audio

In case the source device is not set to stereo or is not capable of transmitting a stereo signal, sound may only come out of one speaker on the TV. Because of this, the volume will sound low. In this case, adjust or replace the source audio device.

  • Method 8: Increase volume offset

If your Hisense TV has a Volume Offset setting in the audio menu, set it to a higher or the maximum value.

Ensure the TV speakers are set as TV speakers in settings and not some other kind of speakers.

  • Method 9: Troubleshoot speakers

Audio issues can be caused by some TVs allowing the TV speakers to act as the centre channel speaker when using a multi-channel receiver in it.

Verify that the right channel audio is being supplied to the TV speakers.

  • Method 10: Check if audio gets routed to other devices

If the TV has audio output jacks connected to a stereo sound system, then the speakers on the TV may be turned off. Remove all audio cables from the TV.

  • Method 11: Select Audio Out and check A/V cables

If the TV has Audio-Out settings in the Sound menu, set it to Audio-Out to TV speakers.

Make sure all Audio/Video cable connections are properly connected to the TV.
