This person would need to know what they have to grab the correct one. Acer links to a tool to tell you, but I just tried it, and it just lists the vendor, and didn't even list my sound card, just my LAN, Bluetooth and Video Vendors.
AIDA64 shows all of my sound devices though, via Multimedia>PCI/PnP Audio, so the OP should download the demo version and hope it shows it. and hope it doesn't edit it out with [Trial Version]
The Trial version can be downloaded here http://www.aida64.com/downloads/aida64extreme270exe
