hi,i had desktop with intel motherboard with chipset G41 and motherboard model DG41RQ.my desktop is assembled desktop with os windows 8 enterprise x64.problem is Audio is not working at all.i visited intel website but I did not find solution.
First check your BIOS! May Audio is disabled or even the BIOS not 100% compatible with W8E. Update BIOS to latest version. Also check driver for Audio Chip if it's not an Intel Audio Chip.
The Realtek ALC662 High Definition Audio is also used on the HP G62 notebooks,so you could try that also
