Description of the new feature/enhancement
Apparently DirectSound is kind of poorly supported since Windows Vista. Wikipedia:
Windows Vista features a completely re-written audio stack based on the Universal Audio Architecture. Because of the architectural changes in the redesigned audio stack, a direct path from DirectSound to the audio drivers does not exist.[8] DirectSound, DirectMusic and other APIs such as MME are emulated as WASAPI Session instances. DirectSound runs in emulation mode on the Microsoft software mixer. The emulator does not have hardware abstraction, so there is no hardware DirectSound acceleration, meaning hardware and software relying on DirectSound acceleration may have degraded performance. It's likely a supposed performance hit might not be noticeable, depending on the application and actual system hardware. In the case of hardware 3D audio effects played using DirectSound3D, they will not be playable; this also breaks compatibility with EAX extensions.[9]
