Does iOS HLS support the opus audio format

I am trying to use hls to play audio and video on iOS devices, the audio format is opus, sliced files use fmp4 format, on iPhone13 ios 17.5.1, it works fine, but on iPhoneX 16.5.1, it does not play, Is it because hls does not support the opus audio format on some versions?

Can anyone help me? I'd appreciate it
