I just finished re-building my computer and performed a clean install of Windows 7 Ultimate (64-bit). I have not had any trouble getting any of the other device driver to install, but my audio does not work. When I mouse over the volume icon in my notification area, it says "No Audio Output Device is installed." I checked Device Manager and there are no missing drivers. The only thing in Device Manager that looks like anything audio related is the "High Definition Audio Controller".
I looked on the Intel support forums for an updated driver and found one that was for Windows XP/Vista. I tried to install it, but it said that the hardware was unsupported by the installation package. I have also tried to run the driver installer in compatibility mode for both XP SP3 and Vista SP1 & SP2, with no results.
I checked around on some other forums as well and saw a recommendation to update the chipset driver, which I have done. All other drivers and the system BIOS were updated to the latest versions. I also checked in BIOS and the audio is enabled. Also, another recommendation that I have tried is to uninstall the "High Definition Audio Controller" and disable audio in BIOS on next boot, then re-enable it after restarting a 2nd time and let Windows find the driver again.
The relevant specs of my PC are as follows:
Motherboard: Intel DG33TL Desktop Board
- From what Intel says, the audio chip is an "IDT 92xx Series"
OS: *Genuine* Windows 7 Ultimate (64-bit)
Any other thoughts or solutions would be greatly appreciated. Thanks!
