Comment (by cypherpunks):

 Tested this on 3 Linux machines, and also Debian and Whonix running in
 VirtualBox.

 For two Linux machines (different models of thinkpads, lspci says they are
 both using the same audio device) I got same values.

 For third Linux machine with another audio device I got different
 fingerprints and AudioContext properties.

 Whonix got their own values.

 Debian running in VurtualBox got same fingerprints as host machine, but
 AudioContext is different.
