// This audio backend uses XAudio2 via XAudio2_7.dll
// This version of the library is included in the June 2010 DirectX SDK and
// works on all versions of Windows, however the SDK and/or redist must be
// separately installed.
// Therefore this backend is available iff:
// * SDK is available at compile-time
// * runtime dll is available at runtime
// Dolphin ships the relevant SDK headers in Externals, so it's always available.
