Which is precisely the same concept as the Silenzio program and the Bluetooth Add-On for NVDA.  You're feeding a constant audio output stream so that Bluetooth never has the opportunity to go to sleep.

All of these things work by preventing Bluetooth Audio devices from going to sleep when no audio is being played, and they do so by continuously playing audio of one sort or another.  The difference between your solution and the others is they are on "endless loop" and are supposed to play "silence" as their sound.
