I was unsure where to post this, and HD audio is being routed through HDMI port which deals with graphics. I just put together a new media PC using an Asus M4A785-M. The 785 chipset supports an ATI HD 4200 on-board gfx. I have no audio thru my HDMI under both XP and Win 7.
1. I first installed the chipset drivers. After reboot I have 2 yellow ? in the device manager, one under "Other Devices" and the other under "Sound", and they both say the same thing. "Audio Device on High Definition audio bus"
2. It says that the VIA HD audio drivers need to be installed before the HDMI. I install the drivers…rebooted, and the yellow ? is gone under “other devices”, but I still have the one left under "Sound". I figure this will be gone once I install the AMD HDMI drivers. Well NO such luck, in fact I get an error whether I use AMD's or Asus's HDMI installer. (H-Error Code) 0xE0000227
The board supports 8 channel HD audio through VIA, VT1708S High Definition Audio 8-Channel CODEC.
Here's where I get confused, I'm not 100% sure how HD audio gets routed thru the onboard gfx, I'm assuming the HD audio from VIA is just being passed through the on-board gfx.
When I go to install the HDMI driver I noticed that is says installing Realtek HD audio 2.8. Why the heck is it installing Realtek drivers for HD audio, if my HD audio is from VIA? ? ? I looked on Asus site and nowhere is Realtek's name mentioned having anything to do with HD audio, just the on-board LAN is by Realtek.
I'm figuring Asus and ATI are giving me the wrong HDMI driver, or something on the board is bad.
