I own motherboard ASUS P6T SE and Windows 7 64bit operating system. In the mentioned system is Realtek HD control panel (Realtek HD onboard sound device) in which I encountered a problem. In fact, I can not provide any inputs/outputs, as I could before on the other motherboard (Gigabyte) with the same software and hardware. Click the left or right mouse button on the input/output and it doesnt work. I have tryed removing the device and software and reinstall it again, but to no avail. Im set to the stereo speakers. How do I resolve this problem?
