Your definition is a little bit different 

Emulation     Forces emulation.

The Emulation setting above forces DirectSound into emulation mode. In this
mode, DirectSound applications run as though no DirectSound driver is present.
All mixing is done by DirectSound in user mode, and the resulting audio data is
played back through the waveOut  API

In linux openal is just software mixing of the 16 voices , so full hardware
accleartion is impossible
