Commands to makeinfo start with @, so I searched for:

$ grep -r @callback scripts
scripts/audio/@audioplayer/audioplayer.m:## @code{player =
audioplayer(@callback_sine, 44100);}
scripts/audio/@audioplayer/audioplayer.m:%!  player = audioplayer
(@callback, 44100);
scripts/audio/@audiorecorder/audiorecorder.m:#%!  recorder =
audiorecorder (@callback_record, 44100);
scripts/audio/@audiorecorder/audiorecorder.m:#%!  recorder =
audiorecorder (@callback_record, 44100);

That's probably where the error is. If you want to document usage with
a function handle, use @@ to insert a literal @.
