		DirectSound natively supports mixing multiple streams, independent volume control, hardware acceleration layer and hardware emulation layer (features which aren't supported by hardware are emulated by software, so the programmer doesn't have to worry if his new l33t code will work right on old sb16).
		DirectSound should be generally fine to use everywhere except for nt4, as long as you have latest DirectX version for your OS and proper soundcard drivers installed.
		DirectSound is preferred over waveOut on win2k/xp, because their DirectSound implementation is relatively good (eats less CPU than waveOut and is free of win2k/xp waveOut implementation glitches).

	Exploring DirectX 5.0, Part II: DirectSound Gives Your Apps Advanced 3D Sound --MSJ, June 1998
		When a secondary buffer is played, DirectSound mixes the data from the secondary buffer with the data in the primary buffer and the user hears the composite sound.
		DirectSound will automatically mix the data from the secondary buffer with the data from the primary buffer to produce the sound that the user hears.
		DirectSound solves this problem by allowing you to set the distance from the listener at which the sound is at maximum and minimum volume.

	Epinions.com - DirectSound (Windows 2000) means Unlimited Channels
		Before Microsoft introduced Windows 2000 and DirectSound, the number of channels that a soundcard had available in its hardware was an important factor when purchasing a sound card.
		DirectSound just mixes the applications' noises with the audio stream on the fly.
		I could run three audio streams at the same time, and hear the resulting cacophony as the three were smoothly mixed together into the computer's single stereo channel.

	The Code Project - A wrapper class for the DirectSound API - Audio and Video
		DirectSound is a COM interface, so the DirectSound object is the COM component object (a pointer to DirectSound).
		The DirectSound object is the core of sound playback and all of buffers, both primary buffer and secondary buffers are created by it, so it must be instantiated before doing any sound play back.
		The DirectSound wrapper class is a generic class, so it is hard to use a windows timer in the class.

	What is DirectSound
		DirectSound is the portion of Microsoft's DirectX API that handles sounds.
		DirectSound also supports 3D sounds through the use of the Buffer3D and Listener3D classes.
		DirectSound enables you to capture sounds from a microphone or other input to the sound card, for immediate playback or storage in a file.

	GameDev.net - Streaming Wave Files with DirectSound
		DirectSound has no concept of when playback of a wave file is complete--it just happily cycles through the sound buffer playing whatever data is there until it's told to stop.
		DirectSound's write cursor specifies the position in the buffer where it is safe to write data.
		DirectSound does not change its write cursor when you write data to a sound buffer--the write cursor always tracks the play cursor and leads it by about 15 milliseconds during playback.

		Directsound is not supposed to change the data, at least if your card offers directsound hardware support (hardware mixing or acceleration), but kernel streming is more secure.
		They show how analog performance with directsound and waveout are virtually identical to ASIO output, both in 16 and 24 bit output mode, for my Audiophile card.
		But on some cards and modes (wave output instead of directsound, for example), it will resample the signal to 48 KHz, and this is a greater change to the signal.

	Gamasutra - Configuring Hardware-Accelerated DirectSound3D
		DirectSound3D is a set of DirectSound API calls that allows for the placement of sounds using a 3D-coordinate system instead of a simple "left-right" pan.
		DirectSound supported basic wave file mixing along with the control of pitch, volume and simple left/right pan.
		DirectSound also supported the offloading of the mixing, panning and pitch-shifting to external hardware, or "audio acceleration." However, due to the limitations of the ISA bus, accelerating the audio meant that the sound card manufacturers had to place (at the time) expensive dedicated audio RAM on their soundcards.

	The Code Project - DirectX 9 - Get Ambient With DirectSound - Multimedia
		It was tough pulling together enough information on DirectSound to get an app working, but I did it, so here is the project I cut my teeth on.
		Though I'll only be reviewing the DirectSound functionality, the project is commented well and you should have no problems figuring out what's going on and how to extend it; or pull it apart.
		Because the DirectX driver for DirectSound could be utilized by a different app running at the same time, this is unavoidable.

		A DirectSound initialize call (specifically CreateSoundBuffer(), I think) can fail if both it and a previously playing sound buffer have demanded a hardware mixing buffer, so that either the hardware and/or a mixing channel for the buffer are unavailable.
