New description:

 IPhone 16 introduced spatial audio. They use multiple audio tracks to
 carry audio. One track is enabled the other is disabled. When specifying
 -map 0:a ALL audio tracks are iterated including disabled tracks.
 In this case, the disable track also have no audio codec set, so
 conversion fails

 ./ffmpeg -y -i ~/Downloads/spatial_audio_test.MOV -map 0:v -map 0:a -c:v
 copy -c:a aac ~/multiaudio.mp4

 Failure:
 [aist#0:2/none @ 0x14a709b50] Decoding requested, but no decoder found
 for: none
