For what it is worth...in my opinion regarding Audio functionality specifically with Sierra, the literal quality between VoodooHDA vs. a working patched AppleHDA system set-up is negligible. My experiences have been that while the latest VoodooHDA v2.90 has continued to operate flawlessly throughout each 10.12 incremental update, the various patches for AppleHDA have broken and have required fixes/adjustments during this same period. There seems to be a generally held opinion throughout the community that using the VoodooHDA.kext some how equates to a sub par/sub standard system and is taking the "easy way out". I will always contend that especially in this realm, why spend hours and/or days beating your head against a wall striving to achieve the preferred perfectionist method when alternatively, you can opt to plug something in that just simply works and move on with your life.
My advise...if you install VoodooHDA and from the get go it just simply works, use it and be done with it.
