If formatting is an option, please consider it. You probably made a mess anyway by installing various drivers, so a clean install will surely fix your problem. When you perform a clean install, your audio output device will be detected automatically and it will work (I have installed Windows 7/8/8.1 about a 100 times on various computers and I have not yet encountered the otherwise). If somehow your audio output device is still malfunctioning, please proceed to the following link.

Once you get there, choose Microsoft Windows for the operating system type, Windows 8 32 bit or 64 bit (depending on your Windows installation), choose Audio for the driver type. Lastly, open the dropdown menu and choose the entry which contains VT1705 (your audio chip).
