Well, here's another drivers to try:
Realtek High Definition Audio Driver for Microsoft Windows 7 (32-bit, 64-bit) - IdeaPad Z570 - Lenovo Support (US)
That's for a laptop but then again, if the inf file has your hardware ID on the list, it should work without problems. Hopefully this will be the solution or else you need to get a Digital to analog Converter (i.e. external soundcard) with SPDIF input to get sound out of your speakers.
