Description W. Michael Petullo 2010-03-05 21:21:14 EST
Description of problem:
I installed Fedora 12 on a Apple MacBook Aluminum (5,1). I found that audio works immediately, but headphone jack detection does not. If I plug in a pair of headphones, audio continues to be played by the laptop's internal speakers and it does not come out of the headphones.

Version-Release number of selected component (if applicable):

How reproducible:
Every time

Steps to Reproduce:
1. Install Fedora 12 on a MacBook 5,1
2. Attach headphones
3. Play audio
Actual results:
Audio comes out of internal speaker instead of headphones.

Expected results:
Laptop should detect headphones, mute internal speaker and play audio through headphones.

Additional info:
I have tried several model options to the snd-hda-intel kernel module.

Ubuntu seems to have a patch that fixes this. See:
