Thanks for the reply. I disabled the 1st and last patch in the screenshot (I'm assuming ticking the 'disable' column is sufficient) and saved the file. Checked and made sure I had an AppleHDA.kext in /S/L/E , no problem there. Ran permissions fix, nothing too glaring there, but still no sound after reboot. Is there some sort of log i could sift through?
