Thanks for the explanation. I missed it because I never though these settings could be that unique.

  Just imagine, if the audio stack exposes the volume level, that's roughly 7.5 bits of uniqueness to contribute to the 33 required to uniquely identity any person on Earth (not that you can expect it to be uniformly distributed, and thus fully usable).

    that doesn't quite work since the volume level changes frequently.

      Yes, it's a poor example in that respect. I meant it more as an explanation of how different attributes of a source all contribute a little but to providing a unique identifier, but you are correct that it's much less useful if the attribute is not static.
