Hello! Thank you so much for posting about this. I completely understand your concerns with the volume automatically turning down. The 2020 QLED and 8k models have added many new features and are equipped with a “Sound Sensor”. If the TV's volume suddenly adjusts, this is related to a new function, the Sound Sensor. You deactivate the feature if you want to. Here are some steps you might find helpful:
1. Navigate to Settings.
2. Select General and then select Intelligent Mode Settings
3. Select Intelligent Mode to turn off all the functions or select each option to turn it off.
f this does not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case-by-case basis, please provide the full model code and serial number of the device as well as your best contact phone number, name, and email.
