Hi guys, I have searched across the forums to see if anyone else is using the same chipset as me and I cannot see anyone else so posting this to hopefully get some advice. I have noticed lots of people with HDMI audio out issues and the realtek audio chipset but no one with the same chipset as me. I have an ASROCK 4CORE-1333FULLHD Motherboard and Windows 7 doesn't appear to allow HDMI audio out with this. I have dualboot into both windows 7 and vista and the default vista drivers are fine in vista but windows 7 doesn't even see HDMI audio out as an option. I have upgraded the BIOS firmware to the latest version, I have tried all of the latest drivers from the ASROCK website and none of them work (if they even load at all - some won't even work with the compatibility wizard running). In vista my audio devices show a Digital output device (SPDIF) and this relates to the HDMI audio out. I don't see this in windows 7. It just shows a single device and says the speakers aren't plugged in (which they aren't since I use the HDMI out through my HIFI system). Since I use my PC as a media center then this is a major issue for me so any help would be appreciated. I don't want to have to buy a new motherboard just for the sake of driver support but I also want to take advantage of the new SKY Player options that are now available in media center.
