I have just updated my computer from windows vista to windows 7 and I can get the onboard realtek sound processor to work. It is a Integrated Realtek ALC662 Audio.
The motherboard is MS-7525 (Boston)
As far as I am concerned I have updated the realtek drivers to work with windows 7. Version R2.70. But they still wont work!
The computer recognises the card but there is a big x where the speaker Icon in the icon tray. When I click on it, it says that a cable is unpluged. But I dont understand this as it is an internal sound processor and therefore not cables are involved.
1. the unplugged cable is the external cable to the speakers or headphone. It only works, if you plug speakers or a headphone in
2. do you use a video card with hdmi output? Then goto control panel / sound and check the standard playback device. It might be set to hdmi, instead of the realtek.
