XAudio2 can call functions provided by the client to notify it asynchronously of certain events taking place in the audio processing thread. These callbacks can be global or specific to a given source voice.

This interface should be implemented by the XAudio2 client. XAudio2 calls these methods through an interface pointer provided by the client in the IXAudio2::CreateSourceVoice method. Methods in this interface return void, rather than an HRESULT. See the XAudio2 Callbacks topic for restrictions on callback implementation.

XAudio2 Code Design, Callbacks or Polling - Graphics and ...
https://www.gamedev.net/forums/topic/627060-xaudio2-code-design-callbacks-or-polling/
Design A - Callbacks: XAudio2 provides a number of callbacks such as when a submitted audio buffer has completed playing. My design here is to create a worker thread in my audio module to perform the heavy lifting (as to not ever block the XAudio2 thread) which can run tasks as soon as possible, or delayed until at least some future time.

My application uses XAudio2 to play audio. When it calls CreateMasteringVoice it passes NULL to the szDeviceId parameter, which according to this documentation page does the following:. If you specified NULL or szDeviceId parameter to IXAudio2::CreateMasteringVoice, then the system uses a Virtual Audio Client to represent the audio endpoint.
Releasing memory allocated for XAudio2 samples

With XAUDIO2, the actual audio data is ALWAYS owned by the application. Playback of the source voice has to be fully completed/stopped before the referenced audio data can be released. In general, DestroyVoice () should work to stop the voice and release it but it can't be called within a callback. See MSDN. Tuesday, October 9, 2012 9:00 PM

“The audio processing thread is stalling because the client’s implementation of some XAudio2 callback is doing things that can block the thread, such as accessing the disk, synchronizing with other threads, or calling other functions that may block. Such tasks should be performed by a lower-priority background thread that the callback can signal.”
