As soon as you get a VIA audio driver v6.0.1.7600 with one of these handy utilities
you'll quickly understand why a manual search is something to be avoided from now on. You must consider the real possibility for one small corrupted driver to lead to big trouble and in some cases even crash your windows. You have nothing to lose; i suggest you experiment with one of these handy programs - see how it works and how it finds/updates the driver(s) that you were searching for. Software and hardware are constantly evolving and we add the latest products very often, thus we must take a little time to make sure they continue working as they're supposed to. Here's another benefit: should you be using an older pc that's unreliable and often freezes i suggest you update all its drivers - this might just get it back on track.
