We noticed that AVPlayerViewController does not always show the "Multi-channel" label in the audio setting in the player when playing a video asset with surround sound as an audio track. (see image)
We only serve in the HLS master manifest a multichannel audio track, like this
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_0",CHANNELS="6",NAME="Surround",LANGUAGE....
Different tvOS versions will give us different outcomes on whether or not the "multi-channel" label is shown
DOES NOT SHOW (the label Multi-channel will not show)
- Model A1842 (tvOS v 17.5.1)
- Model A1625 (tvOS v 16.6)
DOES SHOW (see image)
- Model A1625 (tvOS v 15.6)
This gives us the impression that the label being shown depends on tvOS version.. Any reason why? This is an ideal way for the user to see that the audio track has surround..
