I just got an iBook G4 and I am installed Ubuntu-MATE 15.04 and Debain Jessie on it. Now in MATE to get sound to work I added the snd-aoa-i2sbus module and set the PCM channel to 80 and all was well. However I did the exact same thing in Jessie and I am getting no sound. I added the other snd-aoa module and still no sound. Am I missing something?
