If you're experiencing sound issues with your Samsung sound bar, there are a few things you can check to try and troubleshoot the problem. First, make sure that the sound bar is turned on and properly connected to your TV. If it's still not working, try resetting the sound bar by unplugging it from power for 30 seconds. You can also try adjusting the audio settings on your TV or using the equalizer in the Samsung Sound+ app to boost the bass or treble. If none of these solutions work, then there may be an issue with your sound bar itself and you'll need to contact customer support for further assistance.
