About Airtag for playing custom sounds in iOS16.5.1

[ac0d3r]

I found that the API has been changed to +[CLDurianTask startSoundSequenceTaskWithEncodedSequence:] in iOS 16.5.1,
The Sequence parameter is NSZeroData, and the content is empty.

Then I continued to search upwards for information about the sound* API, passing the Sequence parameter in the -[CLDurianService playSoundSequence: onTag: forClient:]:

CLFindMyAccessorySoundSequence class information: https://developer.limneos.net/index.php?ios=15.2.1&framework=CoreLocation.framework&header=CLFindMyAccessorySoundSequence.h

The SoundSequence is the original data:

I tried to change this data:

  onEnter(log, args, state) {
    log(`-[CLFindMyAccessorySoundSequence initWithType:${args[2]} encodedSequence:${args[3]}]`);
    var data = ObjC.Object(args[3]);
    log(`sound data ==> ${data}`); // [0x04, 0x01, 0x00, 0x00, 0x05, 0x02, 0x00, 0x00]

    // change it
    var bytes = [0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00];  // 2x short round of beeps
    var params_raw = Memory.alloc(bytes.length);
    params_raw.writeByteArray(bytes);
    // NSData['- initWithBytes:length:']
    args[3] = ObjC.classes.NSData.alloc().initWithBytes_length_(params_raw, bytes.length);
  },

but it still didn't seem to work, playing the same sound as before
