I had not thought about a universal. Kluge overkill just for volume, but it would say if it is the remote or the receiver that is week. I wonder if I have an old one somewhere. Yup, found my old Sofa Baton.
I also live the remote mess in my HT. Sony TV, Anthem AVR, Panasonic BD, and mouse and keyboard on the PC. At least I dumped the STB.
Sony will never play with Panasonic. Arrogance. The Sony remote will talk to the Anthem for volume via CEC over the HDMI, but only controls the volume in a small range, so I constantly still need the Anthem remote. I had things working on the Logitech remote ( s) but they all failed in about a year and they dropped them. Sofa Baton was close, but not there. The ultra high price, UR etc, with controllers, subscriptions and dealer only config game I am not playing. Yea a mess. Companies think they are forcing you to buy all their brand but we don;t. Instead, we just get mad at the brands. CEC was supposed to help but it too is an unregulated incompatible mess. The entire HDMI world is a just plain stupid cluster f.....
Got me thinking. I moved everything to the TV using the AVR just as the amp. Maybe with the Sony ( I had a Visio) and no longer a STB, I can get the Anthem to do everything. Naw, it won't know how to switch to the tuner for OTA.
