What's the lightest weight API for windows that allows raw PCM output to multiple speaker configurations (2.1, 5.1, 7.1) on Windows, That's NOT OpenAL? All i need is to stream raw PCM data, no 3d sound or otherwise is required. TIA.

The Windows waveOut functions, maybe?

"In all current versions of Microsoft Windows, including Windows Me and Windows XP, the waveOut API has a limitation that prevents it from taking advantage of all available hardware acceleration. An audio stream that is output by the waveOut API always passes through KMixer, even if the audio device provides hardware-accelerated mixing. If waveOut and DirectSound audio streams are played concurrently, the DirectSound audio streams can still use any available hardware-mixing pins, although the waveOut streams all pass through KMixer and go to a single hardware buffer."

Damn. So, what's the lightest way to output PCM while maintaining HW acceleration?..
