Since I installed the KB3206632 update of December 13, 2016 that brought my installs of Windows 10 Pro x64 up to version 14393.576, (licensing service version 10.0.14393.351), the audio is much better, almost scratch free. I've had various levels of "scratchy" audio on my machines that was mostly tolerable since I've been using RTM Windows 10. Realtek hardware always worked (mostly) fairly well, still scratchy at times but not too bad. The worst performing audio by far of any of my machines has been on one particular laptop, an HP 6710B that was released on August 29, 2008 that came preinstalled with Vista Business and has ADI AD1981HD hardware (SoundMAX Integrated Digital HD Audio). The audio on this laptop with Windows 10 was pretty bad. The last driver made for it by HP is v22.214.171.12440 from November 20, 2009 for Windows 7 x86 and x64, and the KB3206632 update made a vast improvement especially to this laptop using this same driver. I've tried every other driver I could find but this one has always worked the best for me. So I'm wondering if the latest update helped the audio for most of you or not? And if so, was it mostly on older hardware, or for everything in general?
