We now have Audio using the back 3.5 jack and the front headphone and mic work also.
Haven’t tried the HDMI yet.
Had to install the ALC887vdHDA_6Ch_rMic_SPDIF.kext. Install this with KextBeast.
First remove the ALC8xxHDA if you installed the Realtek driver from MultiBeast.
Leave the Realtek8xxHDA enabler and the AppleHDA Rollback. These files are in System/Library/Extensions.
Then reboot and you have sound.
Now, I have to test the HDMI sound, will advise on that.
