Howto install IDT audio driver onto a clean windows install with m17x r3 + 780m. When I first installed my 780m I had a good Windows 10 setup and didn’t have to mess with audio at all. Now I did a clean install of Windows 8/8.1/10 on my new ssd. After the first reboot of install, windows logo loads, then a random solid color, system beep every 3 minutes or so. After disabling the idt audio in bios, I installed and booted into windows 10, yay. Installed system drivers, nvidia drivers (video driver mod instructions: https://www.techinferno.com/index.php?/forums/topic/2878-m17x-r3-gpu-upgrade-to-gtx-780m/&page=10 get driver from nvidia and find/replace in nvdmi.inf), but audio driver won’t install because it is disabled in bios. If you enable audio in bios and reboot goes through windows logo loading then black screen. (might have been random colors if I rebooted again) Download drivers from dell support site (they are win7 drivers but install to win10, some drivers are already installed on win10) except nvidia driver. The Clean Install: Disable audio in bios, install and boot windows. Install drivers per: http://alienwareusersupport.weebly.com/upgrading-to-an-ssd.html To install the IDT audio driver: Reboot into safe mode (Win10: settings, update, recovery, advanced startup: reboot. Choose Safe Mode option after reboot.) On reboot into safe mode, press F2 to go into bios when you see it (after advanced startup reboot). Now enable IDT audio in bios. Save and continue from bios. Windows loads into safe mode. Now install IDT audio driver. Success! Reboot. You might be done at this point! On the first reboot, after showing Windows login screen briefly, my screen went black. I waited a minute then held power button 10 seconds to turn off. Turned back on and Windows booted up and I logged in and I’ve been running successfully for 5 minutes so far! Audio plays fine. When I plugged speakers into jack Windows downloaded and installed .net 3.5. Now I’ve got IDT audio notifications. Good luck!

This find and replace on nvdmi.inf worked for me using the newest GeForce drivers (GeForce WHQL ForceWare 358.50 and 358.87) on Windows 10 64-bit. I used the laptopvideo2go modified inf when I installed 358.50 the first time in addition to modifying the nvdmi.inf and that installed fine. I did a clean install when I updated to 358.87, modifying the nvdmi.inf but not using the modified inf from laptopvideo2go and this also installed fine.
