This is a official problem after the osSierra installation I loss the volume control with my integrated Audio (Realtek ALC889A) on my iMac8,1 (2008 early)

Has somebody a solution?
thx
I installed os Sierra with the patch on my iMac 8,1.
Now I need a AirPort driver (BCM 4321 kext) that works on OS Sierra.
I know this is a new problem but I suspect that others also are interested for a solution.
Thanks!
