Windows 7 64-bit and Sigma Tel high definition audio CODEC problems

I recently upgraded my work laptop to the latest and greatest edition of Microsoft’s primary operating system Windows 7, 64bit. Seeing this is the first time I am migrating fulltime to a 64bit Windows system I have decided to keep my old 32bit Windows Vista partition on the same laptop using dual partitions. Everything with the installation of Windows 7 has worked flawlessly accept for one major problem has an easy fix.
