your Mac and to the virtual machine. If this sound card is 5.1 surround-capable, the virtual
machine output device will reproduce 5.1 surround sound. If the sound card does not support
5.1 surround sound, the virtual machine output device will reproduce stereo 2.0 sound.

how to do that, please refer to this operating system documentation.
