A modified sound device is not just another laser DAC. It's a sound device. It is generic. It is supported by every OS and every app that plays multi-channel waves. It exists totally outside of laser projection technology. That's the whole point! LaserBoy is all about letting people explore the possibilities of laser display and other vector based artforms in a totally generic way. Do it yourself!
LB does not stream to any kind of DAC, sound device or otherwise. It just reads and writes files. You have to play the waves it makes with an application for playing waves.
