Corsair 1500 sound surround has nothing to do with your on-board sound card or on-board video.
You have to install the included software or download it from Corsair homepage to make the Corsair 1500 surround sound works.
The headset surround sound is working via software emulation just like my Logitech G35 (it does not need any sound card).
You can buy it and use it after you install the software, no need to worry. It will work
