Any help will be greatly appreciated.Cheers,R.you macs alc889a there is no such thing as mac only supported alc885, also if it is a mac, i mean real mac then the pinconfigs are setup through bios and kernel called vendor widgets and mac have over 30 diffrent setups for alc885, if you wiped your mac and put linux on you would have to remap you pin configs in alsa to match a mac layout.
