From ESPEasy v2.0.0-dev6 (in the testing plugin set) its also possible to play a tone on a pin, via a speaker or piezo element:

Melodies and ringtones
From ESPEasy v2.0.0-dev6 (in the testing plugin set) its also possible to play melodies via [RTTTL]
(don't forget to remove the spaces)
http://<ESP IP address>/control?cmd=rtttl,14:d=8,o=5,b=180,c6,b,c6,p,g,g-,p,f,b,c6,p,d6,p,g,p,c6,b,c6,p,d6,p,f,g,g-,4p,g,f,4d-
This plays a melody on pin 14.

To make a boot-sound on startup, create a rule like this:
On System#Boot do rtttl,14:d=10,o=6,b=180,c,e,g endon
