Changing audio channel in AppleTV app

[g0141]

Hi. Apologise if this has already been mentioned but couldn't find in a search.

Using Apple TV app, I'm sure I used to be able to select and change the audio channel on recordings and live TV by pressing and holding the track pad. This resulted in a drop down menu and ability to choose which audio channel. This no longer happens, long press now simply pauses. Am I doing something wrong?

Apple tv app 3.5 (build 25)
tvos.15.3

Same here, unfortunately:

AppleTV 4K 2G (A2169) on tvOS 15.6.
NextPVR app 3.5 (25)
NextPVR server 5.2.7.220410

Is this feature (obviously introduced in 3.1) maybe depending on the remote device connected to the AppleTV?

We are using the silver "Siri remote 2G" and a long press on the click pad doesn't bring up a menu to select the audio track (the recording definitely has more than one).

Thank you for your help.

If you can supply an example recording, I'll check what's happening.
