I have just installed Windows 8.1 Pro, and now I'm facing some problems here. I tried to install Realtek HD Audio but after installing, It just not working. Can anybody help me. I am very appreciate.
Are the Realtek drivers you installed for 8.1? There are many cases where Win 7 or Win 8 drivers won't work and only Win 8.1 certified drivers will work (or work properly).
Uninstall the Realtek and drivers, in the Device Manager. Restart the PC and Windows should install the generic High Definition Audio Device (Drivers). Then check the Sound Panel/Playback section. The "Speakers" should be set as default audio playback device. Does sound now play?
