Followed directions, but no sound on Mid-2012 MBP

I followed all the step-by-step directions (including Sysprep) posted elsewhere on the twocanoes.com site to transfer a bootcamp partition from an Early 2105 MBA to a Mid-2012 MBP. Everything went fine, except I have no sound when booted into the Windows 10 bootcamp petition. Yes, I did download the bootcamp drivers and ran the setup, which correctly installed all the hardware drivers, except the sound driver. I’ve tried to find the correct sound driver manually with no success. Any suggestions would be appreciated. Thanks. – Carl
