This time i'm posting this question for my friend. He had old intel D945GCPE Motherboard on his system. He saying that he was very happy with his 5.1 Sound system When he was running on WinXP. But recently he had updated his system into Win7.Now the motherboard doesn't support 5.1 channel audio. There is only a headphone in Playback devices. His Sound driver is Realtek 2.33a. yesterday he downloaded this Driver (for W7) From intel's download center. after installing that makes no changes... Help
The page that you mentioned saying "To be sure you obtain the full features/customizations provided in your original audio product, please download the latest drivers from your system/motherboard manufacturer's website"
i had downloaded that codec from manufacture's website... but problem still exist
