** Summary changed: - Regression: Headphone socket does not work on MacBook Pro 3.1 + Regression: Headphone socket/Microphone does not work on MacBook Pro 3.1 - need to hint the module options manually
** Description changed: - Intel HDA in 2.6.27 seems to be broken. In .26, plugging in headphones - would automatically mute the speaker and use the headphones. - Occasionally the state of the speakers would break, but you could toggle - it manually through the ALSA driver's "Speaker" switch. In .27, the ALSA - mixer controls are much less, and this option is missing, and there are - no others to choose whether to use the headphone port or not. + The sound device model probing is broken in 2.6.27. As a result, the + sound device is missing large functionality, including any use of the + microphone, and headphone port. + + Using the model=mbp3 option on snd-hda-intel as described here: + http://git.alsa-project.org/?p=alsa- + kmirror.git;a=blob_plain;f=Documentation/ALSA-Configuration.txt;hb=HEAD + restores the previous functionality. + + Workaround: append the line "options snd-hda-intel model=mbp3" to + /etc/modprobe.d/alsa-base and reboot.
