Hi all
I'm new to the forums. I've been googling for hours on here and elsewhere, but can't find an answer to my issue.
I have an HD4350 graphics card, which has a Realtek chip for sound built on. It has an HDMI output and should, if its working, output 7.1 audio over HDMI. My onboard sound also uses Realtek, and that works without issue. However, I have that turned off in BIOS because I want to use the sound controller on the ATI card (for HDMI).
I know I have to load the ATI Catalyst drivers, then the Realtek HD controller, then the Realtek ATI HDMI driver in order to get that to work. Catalyst installs fine and works beautifully for video. Catalyst recognises my display as an HDMI.
The problem is that when I load up the Realtek drivers (R2.15, but I've also tried previous versions with the same result), it instals without error. But the Realtek manager does not appear in control panel, nor does any sound controller appear under 'sound and video controllers' in device manager.
What does appear in device manager for the card, under 'System Devices', is the MS HD audio controller. This gets loaded up part way through installing Catalyst and, once Catalyst is installed, will automatically load as a 'preconfigured driver' on every reboot, even in safe mode, and there is nothing I can do to stop it (easily). But it is only in system devices, not sound and audio controllers. I have tried manually overriding that driver with Realtek but Vista says the driver is up to date.
I have read that some using XP have had success in loading Realtek by manually deleting the MS audio controller files (hdaudbus sys and inf, and hadaudio sys and inf) from the driver folders. I assume I would need to delete them from the driver store as well.
But I also read that those files are actaully necessary in Vista. Before I mess about too much deleting my system files, I'd like to know if that has a chance of helping, or whether it is another red herring (of which I've seen many over this issue). Can someone please tell me whether MS HD audio controller should be installed in system devices if you are using the Realtek drivers on a PCI card? I know for onboard Realtek it is required - it sits in the system devices and the Realtek HD audio appears under sound and video controllers.
I don't have another PC I can try my card out on myself, so any thoughts on this question or other suggestions to solve my problem most welcome.
Thank you!
