Siri Remote volume buttons not working with Samsung HW-H450 Sounder via IR
I've tried programming my Siri Remote to control my Samsung HW-H450 Soundbar, but it fails to work. I know the IR is working in the remote, as I tried programming the volume up button to turn my TV on/off, and the volume down button to change the TV HDMI input, which worked. Why would some IR signals work, and others not work?
