I have installed Windows 8 on a machine with an Asus M4A88TD-M/USB3 motherboard which has an ALC892 sound chip. I can't seem to get the sound chip to work correctly. I've installed the latest driver 2.70 and the audio devices in the device manager look like this:
The upper device uses the Realtek driver but the two lower once use a Microsoft default driver. I've tried to install drivers for the two lower devices manually but there are no compatible ones among the downloaded Realtek drivers (At least Windows claims so).
Anyway now the sound settings look like this:
You can see that the Realtek device is missing. Also the Realtek Soundmanager doesn't seem to work correctly:
The onboard sound is activated in BIOS and works just fine on the Ubuntu I've installed in dual boot.
Does anyone have an idea how to solve this?
