I got a problem on my onboard sound card. Today, when I truned on my computer, I found the sound device is different from the one I use usually.
When I clicked into the control panel, I saw these gray words next to the realtek HD device "not plugged in". I am wondering why does this problem appear, as the onboard sound card is un-removable.
I tried to uninstalled the driver, and then installed the lastest driver, but still does not work.
Hopefully it is not the hardware's problem.
