No sound support on https://www.fantasy-lands.net/Col-Tracker/ #23203

Describe the bug

This SWF applet is used by a JavaScript "Sound-Tracker" to play sound (emulating an old 8 bits chip).

The SFW is supposed to be driven by the JavaScript code, but it can play sound by itself when pressing one of the blue buttons on the top ("Donkey Kong" to "Spy Hunter")

While on the page, click the "Show Player" text button on the top right of the page to display the player module.
Then, clicking on a game name (example: "Donkey Kong") should play music; at the moment it stays silent.

Note: The music are played "from scratch", generating audio square wave (I mean they are not some embedded mp3 or wav resource).

Expected behavior

I expect 8 bits like music to be heard from the computer speakers when pressing one of the top row buttons.
