You have to edit the supertet.cfg file with a hex editor to get the sound.
The first config I used didn't even have a button for music.
The second had the button but the music was always off.
Edit the first line of the supertet.cfg file from this:

00000000  04 00 0A 1A 00 00 00 00 00 00 00 00 00 00 01 00

to this:

00000000  04 00 01 00 00 00 00 00 00 00 00 00 00 00 01 00

then you have the option to turn the music on and off.
