New Steam Controller sings songs, plays Doom

Valve's new Steam Controller, despite lacking a speaker, has demonstrated surprising audio capabilities. Users have discovered ways to make the controller produce sounds, ranging from simple ringtones to complex musical pieces and even game audio. One notable example shows the controller performing the 'Ground Theme' from Super Mario Bros. 2 and 'Still Alive' from Portal. It has even been made to play audio from the game Doom. This functionality stems from the controller's internal hardware, allowing for creative audio output beyond its primary input functions, appealing to tinkerers and enthusiasts.
