Siri Remote Volume/Mute Not Working
After the frustration of going through 3 remotes on my AppleTV HD, I just settled on using my iPhone as a remote for a while. However, I grew tired of having to use an additional remote to control the volume, so I finally decided to get the new Siri Remote. It paired instantly to my AppleTV, but the volume controls no longer communicated with my Sony powered speakers. I went through the process of learning the volume +/-/mute controls again using the Sony remote, and the AppleTV received the IR signals just fine. However, the new Siri Remote still won't control the speakers. I verified that the IR on the remote works by directing it at my iPhone's camera which picks up the IR light. Also, it's able to control my TV's volume via IR when set to do that, which I obviously don't want.
I've tried everything from temporarily unplugging AppleTV, updating tvOS, fully charging and then re-pairing the Siri Remote. I even replaced the batteries in my Sony remote to ensure it was sending a strong signal to learn from. Ironically, my old broken AppleTV remote still controls the volume (that's all it does).
It appears my new Siri Remote is sending IR signals to control the volume, just not the right ones. So now I'm back to using two remotes again. What gives, Apple? If I can't get this resolved, I'll be sending the new remote back.
