Why are there iPhone speaker choices now?

Fine, but you are telling me one thing and a senior Apple agent is telling me otherwise, so I am interested in seeing some evidence that this is expected behaviour when it never ever did it before. And I had 12.4 before I updated to 13 too.

Not asking the iPhone to read my mind, just don't want it to offer me choices I have no desire to use, and, in fact, don't even work!! I am near my iMac and my Apple TV is in the other room and choosing either of those audio options doesn't even play the audio on those devices if I select it, so it's a useless option anyway, even if I did want it, but I don't.

As I say, it would be fabulous if you could point me to any evidence that this is a feature. It must have a name. There must be something about the feature in documentation somewhere.

"One thing you might try is to go to Settings/GeneralAirplay & Handoff and set Automatically AirPlay to TVs to OFF. That won't help if you have a Bluetooth device connected, but it might if you don't."

I don't have this setting on my iPhone. I have Handoff, but that is just either on or off and it refers to using apps on all devices, not audio.

I looked in the manual and there is nothing. Only thing I could find was this: https://support.apple.com/en-ca/guide/iphone/iphb152a5c6/ios but it does not refer to audio choices for phone calls. If you can find it, I would very much appreciate your sharing it here. Not asking you because I can't be bothered because I tried, but can't find anything which confirms this as intended behaviour. I don't mean to be pedantic, but I want to show this to the advisor who swears it is not supposed to be doing that. He even researched it with his senior tech (which doesn't mean they are all wrong, but...)

I’m sorry you are annoyed. It’s not that I don’t believe you, it’s that I have senior Apple techs telling me otherwise so I am trying to get some documented evidence in order to address this with them.

Oh my gosh! This is actually a real practical answer to the issue. Thank you!! That does seem to have worked for the Apple TV option. Fingers crossed it stays that way. I did have to restart the phone to make it go away as well.

The only thing now is that my iMac sometimes comes up as an option. How do I unpair the phone from another Mac computer in the same way? The only thing I can find is about disabling Handoff, but Handoff is a different thing. It's purpose is to allow you to continue working in an application from one device to another, like finishing an email. I don't want to switch that off, I just want to switch off using a computer for the phone's audio on a call.

Thanks for the suggestion. I see some devices listed there, like my trackpad and an old pair of headphones I no longer have, but no iPhones. On the phone, no computer is listed.
