Flex doesn't work with bluetooth volume, only tv volume
I just set up my flex, and it automatically paired to my tv. Which is good, however I have my TV volume turned off completely, it's disabled. So I connected the bluetooth speaker to the Flex, however everytime I use volume up or down it goes through the TV and I get the tv's message "you must turn on volume". I want the flex to work through my Bluetooth speaker only and not the TV. I cannot seem to find anything online to solve this. How do I get the volume to be able to be controlled through the bluetooth speaker.
For clarification it's the Insignia Bar 2.1-Channel 80W soundbar system with wireless subwoofer and it is connected via bluetooth to the flex.
