I was using intel DG965 motherboard with onboard 5.1ch sound card. I have been using it flawlessly in Windows XP. However, when I upgraded to Windows 7 x64, it automatically installed a 'High Definition Audio Driver' for me which only the front 2 speakers work. In the control panel, I can only choose 2ch speaker, it does not have an option to activate 5.1ch.
I have tried installing Realtek HD Audio Codec 2.41 (Vista_Win7_R241_x64). However there is no change at all. I believe there should be something called Realtek Audio Manager, but I cannot find it. Is there anymore thing I need to install?
The realteck audio codec I have is:
Vista, Windows7 Driver(32/64 bits) Driver only (Executable file) R2.41 2010/1/22 53673k
Before your reply, I have installed Intel SigmaTel Audio Driver:
It installed well and I can open the audio manager. It lets me configure the 3 holes to be input / output. However, when I set all holes to be Centre, Front and Rear speakers, still, only Front speakers work
Prior to migrating to Windows 7 from Windows XP did you run the Windows 7 Upgrade Advisor?
