No sound output on MacBook (HDA Intel)
Last modified: 2007-11-30 17:11:35 EST
Description of problem:
No sound output on MacBook from either headphones or internal speakers
Version-Release number of selected component (if applicable):
kernel-2.6.16-1.2289 from Rawhide (16-Jun-06)
Steps to Reproduce:
1. aplay /usr/share/sounds/shutdown.wav
No sound output from internal speakers or headphones.
Sound from internal speakers or connected headphones.
This problem is fixed in alsa devel repo
It seems that the current git5 patchset for the kernel contains the necesarry
ALSA patch. As soon as the FC6 kernel hits git5 I will test if it resolves the
Sound is working now.
Update: sound through the headphones is working as well but inserting the
headphone does not disable the internal speakers.
With the current kernel (2.6.17-1.2462.fc6) and ALSA (alsa-lib-1.0.12-1.rc1
alsa-utils-1.0.12-1.rc1) sound is working properly on the MacBook. Inserting the
headphones disables the internal speakers. When removing the headphones the
speakers are enabled again.
Microphone input does not seem to be working though.
