Comment 140 for bug 337314

@Alex Murray: the patch seems to work which makes you the hero of the day! :) But here are some awkward things I've come up with (using Arch Linux - on Macbook Pro 5.1 - btw):

1) I don't know if this's related with the patch or not but alsaconf cannot found any sound cards, but the kernel seems to recognize and load all the necessary modules for the sound card

2) When headphones are plugged in, I've to mute and unmute the Headphone channel a few times in order to get sound from them. I don't know why this happens.

But all in all, the jack sense is working! :)
