HP Envy Recline 27
Windows 10 Version 1511 (OS Build 10586.14)

While trying the solve the windows 10 no audio after sleep problem, I noticed that since the 1511 Upgrade and the windows 10 RollUp the following week, the Playback Enhancements tab had moved from the IDT High Definition Audio Codec properties to the USB Audio Codec properties. I don't know if this problem is related to no audio after sleep problem, which I assume is a power management problem.

Both drivers are up to date and since the windows upgrades there are no roll-back option on either.
I'm considering uninstalling both, but unsure on order of reinstall.
