WDM = Windows Device Manager? (from control panel) i had the same problem here "Driver Version Not Found" but after that i had a compatiblitily window popup so i try to reinstall the way windows 7 think was best and the process start again without the msg "driver version not found" but in the middle of the process a message popup : "Loading of MUI resource failed. the application will exit." after rebooting i noticed that sound was working but only from the green jack. also the audio control panel, and volume panel didnt work. am i missing somethink here?
