ASUS P5E-VM HDMI audio

While I am aware that there are several threads on this topic, they are all far too advanced for a newbie like myself.

Basically I am trying to get audio through HDMI. The video is working fine, but no audio. I am running a ASUS P5E-Vm HDMI on G35 mobo. The HDMI is running through a Marantz SR5003 Dolby TrueHD / dts-HD Master Audio AV Receiver.

I`m not sure what other info is required, but any help that can be offered in simple terms is greatly appreciated.

Yes, I am running the HDMI through the onboard HDMI port of the motherboard. As far as the drivers, I believe I have installed all the audio drivers for the motherboard. If I look under sound, video and game controllers on the device manager, I see:
- Audio Codecs
- Intel High Definition Audio HDMI
- Legacy Audio Drivers
- Legacy Video Capture Devices
- Media COntrol Devices
- Realtek High Definition Audio
- Video Codecs

Also, I have just noticed, under Display Adapters, I have 2 listings for Intel G35 Express Chipset Family. Under device status for both of these, it says "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing." When I try to update the driver, it says it could not find a better match for the hardware.

I'm not sure if this has any effect on my HDMI audio, but I assume it needs to be corrected. Any help on this issue would be appreciated as well.

Is graphics driver the same as display adapter? If so, its version 7.14.10.1329, date 9/13/2007. The HDMI audio version is 5.10.0.1032, date 7/24/2007.

Wow. Apparently that fixed both my problems. Finally have audio through HDMI. Thanks

Now, how do I determine the best video settings for this system? The monitor is a Hitachi 42" Plasma TV.

for the TV? 1080p
