NVIDIA GTX460 'no audio devices installed'

Hi guys,

I just bought a GTX 460 card and want to use the high res. audio (DTS-MA/TrueHD bitstream) from the card. I tried to install and reinstall the NVIDIA driver over and over again but I just keep getting 'no audio devices are installed' under sound options. The strange this is that the NVIDIA control panel lets me choose my receiver (Onkyo TX-NR5008) under the setting 'setup digital audio' option 'HDMI'. At my Device Manager there is shown 4x 'NVIDIA High Defenition Audio' under 'Sound, video and game controllers'......

Setup:
Asus GTX460 with 295.73 driver (also tried the latest)
ASrock H61M-ITX board (http://www.asrock.com/mb/overview.nl.asp?Model=H61M-ITX)
Windows 7 64-bit with SP1 and all the latest updates
Latest DirectX version
GTX460 connected to my Onkyo TX-NR5008 AVR with mini-HDMI->HDMI cable
Onboard audio disabled in bios

If more information is needed please let me know.
Hope someone knows the solution for my problem.

Thanks!

The only separate driver I can find is a really old driver that only mentions a bunch of old chipsets. http://www.nvidia.com/object/hdmi_audio_xp_vista_win7_1.00.00.59.html

First, clean out all the installed drivers (http://www.guru3d.com/category/driversweeper/ or if you're willing to spend $10 http://www.drivercleaner.net/) , including any nVidia driver that Window might have pre-installed. Then reinstall the driver from nVidia, and if it has an "advanced" or "manual" option, use that and make sure HDMI audio is checked (if it is an option at all - I only know it's an option in AMD's drivers; I haven't had an nVidia card in a Windows system in several years).

I think you missed the driver cleanup part.
