Neither does modern Linux, sadly. The older SunOS-style audio devices still exist in the kernel as an emulation, but aren't loaded by default (and tend to have weird behavior vs. other parts of your distro's audio stack). The ALSA framework is the modern equivalent. It's much more featureful, but its device API is frustratingly opaque. So much so that the only "supported" interface to the driver is the libasound userspace library. This, too, is low level and opaque. So you're really supposed to use the pulseaudio middleware to actually play and mix your audio stream. And even then, the pulse API is basically PCM-only, and your stream is probably sourced from something encoded. So you really want to be using gstreamer to generate your stream and take advantage of existing codec plugins (and hardware acceleration, etc...). And even then gstreamer is opaque, so all the toolkits have wrapper APIs.

Sigh. The days of being able to spit sounds to a char device are basically over. We have more powerful software now with far more capability. And that kind of sucks, sometimes.
