I got the same with Ubuntu 13.04 I've found (and written down) a partial solution here (in french) : http://www.e-glop.net/main/Installer_Ubuntu_sur_un_MacBook_5,2_en_Live_USB#Le_port_.22.C3.A9couteurs.22
it consists in using hda analyzer from the Alsa team, and to switch a value for the headphones PIN... the problem is now : how to make it reused everytime the computer boots or get out from suspend... for now, my solution works well when you "rmmod snd-hda-intel" then "modprobe snd-hda-intel" but it doesn't work when the computer boots or wakes up. need some help on that... I'm lost... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971561 Title: [MacBook5,2, Realtek ALC889A, Green Headphone Out, Rear] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/971561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
