Can’t tell you how long I’ve been waiting for this to be added and how other streaming devices can easily do this, but you can now control tv speaker volume via HDMI CEC, which means you can control your tv speaker volume. Before you could only control TV speaker volume with IR, so wouldn’t work for iPhone. And if you wanted to control your tv volume via iPhone, you had to have a sound bar connected via HDMI to do so. Was really annoying that I couldn’t control tv speaker volume on my other TVs that didn’t have sound bars, like my bedroom, kitchen, office etc. Should work for any tv with CEC I’d think but maybe not. All my Sony TVs are within 2 years old and do.
Definitely not new. This has been a feature for years.
I’ve been able to do that for a while
You’re years late 🤦
This has never worked for me
How do you do it? Did they add a new button on the iPhone controller?
You use the volume buttons on your phone.
Use the physical volume buttons on your phone.
I finally upgraded by TV and am really enjoying being able to use my AppleTV > HomePod Stereo Pair as the audio output for any sound sent to the TV by other devices and game systems.
Been working for years changing my tv volume with iphone through Apple TV. There must have been something smelly in your setup
