Solved Clean install - High Definition Audio Device listed twice!?

[0pTicaL]

I am running a clean install of Windows 7 Pro x64 SP1 on a Asus P8Z68 Deluxe. When I first installed Windows, first thing I did was install Intel's chipset drivers and IRST drivers, then all other mobo drivers. Checked Device Manager and everything is detected.

Here's where it gets weird, I had a MSI R6970 installed on a workbench and when it was time to put everything in the case the video card wouldn't fit.

I had spare GPUs lying around so I used a ATI 5450 in the meantime. However once I installed the 5450 and booted the system, then restart after detection, device manager is showing there's a unknown High Definition Audio Device in device manager.

I tried uninstall Realtek's drivers (R266) and reinstalling them, didn't work. I tried installing 'ATI HDMI Audio Device' from Realtek's website, didn't work.

Now I'm starting to think, does this have something to do with AMD's drivers?

You're correct - this ATI card supports HDMI 1.3 which can transfer video and audio over a single cable. For that reason the card has its own audio device onboard, which requires drivers from AMD.

It will not conflict in any way with your existing Realtek audio, it's simply an additional audio device you may instruct Windows to use instead.

The problem I'm having now is how to get it to detect? I tried uninstalling Realtek and AMD's drivers and reinstalling, doesn't work, '?' is still there.

The drivers for the videocard should take care of this for you. To download them, go here:

AMD Graphics Drivers & Software

The drivers installed by Windows tend to be more basic and not include the audio device component.
However, if you're simply going to use your laptop normally and not connect it to a HDMI output device such as a TV, then you might simply ignore the missing audio device as it does no harm to your system.

Again, the ATI HDMI audio device is completely separate from the Realtek audio and there's no need to uninstall the Realtek drivers.

Delete/uninstall the driver "ATI HDMI Audio" using the Device manager. Reboot.
Use the link that Corazon posted and download the CCC package which has the AMD HDMI driver included.
If all goes well, your driver should read "AMD High Definition Audio Device"

I did exactly that and it's still and it still undetected. I tried disabling onboard in the BIOS and it goes away so I'm stumped as to why it shows up twice in Device Manager.

The AMD audio is for HDMI, Realtek is for other (on board) audio, speakers, headphones and such. It is normal and causes no harm, here's mine...


...so twice ain't so bad.

 

[0pTicaL]

The difference is yours are detected, I can't get mine to detect.

I'm going to do a reinstall since I haven't started putting any serious information on the OS.

I just thought this problem was weird since swapping out my 6970 for a 5450 shouldn't cause any issues because AMD uses unified drivers. Now that it's happened I don't know how to remedy it and being a perfectionist it's annoying having a exclamation mark in Device Manager.

Figured out the problem! It's Sandy Bridge's integrated audio. Run Intel's integrated display driver, reboot and it will detect.

Help me out here guys ) like him i don't an Mananger

hey guys please help with my prob

What is the Intel integrated display driver?

Figured out the problem! It's Sandy Bridge's integrated audio. Run Intel's integrated display driver, reboot and it will detect.

I have a P8Z68/GEN3 Deluxe motherboard and am on a fresh install of Windows 7 SP1 x64. I have two HD Audio devices: one for the Realtek Audio and one other that "cannot start" (maybe for the Sandy Bridge HDMI Audio?) If possible, could you describe in more detail what you had to do? I tried uninstalling the Intel HD Graphics Family display adapter from Device Manager and reinstalling it after rebooting but that did not solve my problem.

You got this driver from the CD that came with the motherboard? I can't seem to find the Intel integrated display driver for some reason.

Any help you can give would be great!

Thanks,
mahi

After two hours of digging around, I went to Intel's site. They have an auto-detect drivers option. I ended up reinstalling the display driver from there. I followed Support for the 2nd Generation Intel® Core™ Processors with Intel® HD Graphics 3000/2000 (I have an i5-2500K so this may not apply to everyone) After that, I downloaded Intel Graphics Media Accelerator Driver for Windows 7* 64, Windows Vista* 64 (exe)

I must have had a problem installing the driver the first time around.

Glad to hear you figured it out. The auto-detect drivers option on Intel's site is a great help since it was very difficult for me to find the exact drivers needed on older systems and on newer ones.

i have a m2n-268 motherboardc an changed processor from amd athalon 64 x2 3800+ to amd athalon 64 x2 6000+ and running 4.00gb ram ddr2 5300 and win 7 ult 64 and showing amd hd audio like others in the dev mgr. but cannot get it to recognize speakers plugged into grteen output port in back or the green port in front of tower now. have tried drivers for things lf all sorts all over and cant find any that get it torecognize the speakers now. am using a ati radeon hd 4670 1gb graphics card btw. any suggestions?

High Definition Audio Device listed twice cannot start. Fixed

P8Z68 Deluxe - Had this problem and resolved it disabling the Intel graphics in BIOS

EFI BIOS Utility Advanced Mode
Initiate iGPU < disable this item

You will not be able to use LUCID's VIRTU with the Intel graphics disabled, however I found it of little use. Your results may vary.
