HI there! I am sorry to hear that you are experiencing issues with the sound occasionally dropping from your soundbar. You may first want to check the cable connection of the soundbar to the TV or external device to ensure it is secure, and properly connected to the correct port.
In addition to checking the connections of the soundbar, please make sure your soundbar is using the latest firmware Version. Updating the firmware on your soundbar gives you all the benefits of the latest improvements. When the Soundbar is connected to the Internet, Auto Update allows software to update automatically even when the Soundbar is turned off. You can also update by using the SmartThings app.
You may also want to initialize your soundbar by pressing the - and + (volume) buttons on the top of the soundbar at the same time for at least 5 seconds. The light indicator on the front of the soundbar will blink 4 times and the soundbar will be reset. Please know, this will reset all settings on the soundbar back to default; any sound adjustments will need to be performed again.
