AVPlayer HLS live stream level meter (Display FFT Data)

Sadly, using an HLS stream with AVFoundation doesn’t give you any control over the audio tracks. I ran into the same problem trying to mute an HLS stream, which turned out to be impossible.

The only way you could read audio data would be to tap into the AVAudioSession.

EDIT

You can access the AVAudioSession like this:

[AVAudioSession sharedInstance]

Here’s the documentation for AVAudioSession
