Red Hat Bugzilla – Bug 570974
MacBook Aluminum Install: Headphone detection does not work
Last modified: 2010-03-06 18:02:28 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):
Steps to Reproduce:
1. Install Fedora 12 on a MacBook 5,1
2. Attach headphones
3. Play audio
Audio comes out of internal speaker instead of headphones.
Laptop should detect headphones, mute internal speaker and play audio through headphones.
I have tried several model options to the snd-hda-intel kernel module.
Ubuntu seems to have a patch that fixes this. See:
Fixed in kernel-220.127.116.11-67.fc12.x86_64.
