Emporium you are the BEST!!
Ok what I found out.
When I checked the volume buttons with my camera (as you suggested) they were not putting a signal out.
I found out this remote goes to sleep after some time, and the only way it wakes it up again is if you hit the power button that turns the TV on.
Once the remote is awaken and only then, will it send a signal from the other buttons on the remote.
Once I found this out it was very easy to program the BT350 to use the other buttons from the Insignia Fire TV remote.
Buy the way I did have it setup as you suggested ( If programming does not work, another option for you would be to change your buzz box to disable "max volume" and that way the main volume buttons on the b350 would allow the buzz box to output a variable audio level. So you can then set your TV volume to something like 60% or 70%, and then the buzz box would output a variable level and when it is at max, it would represent the level you set on your TV.) I just wanted a way I could also control the TV volume just in case I would for some reason need to raise or lower the TV volume.
Thank you once again for your superb help Emporium, I can ALWAYS depend on you!!
