Hi, I have a Macbook Pro 1.2 .With ubuntu 12.04, the sound works, but when I plug in headphones, I have sound both in headphones and internal speakers. I tried to add "options snd-hda-intel model=macbook-pro-v1" at the end of /etc/modprobe.d/alsa-base.conf But it is not working better. The soundcard on that laptop is a SigmaTel STAC9221 A1 Is there something else I can try to get the sound working correctly?
