[Pkg-alsa-devel] Bug#770122: alsa-base: Headphone Jack not working on Macbook 5, 2

[Teutone]

Package: alsa-base
Version: 1.0.27+1
Severity: important
Tags: patch

Dear Maintainer,

* What led up to the situation?
I was happy to see that after installing the latest Debian Jessie on my Macbook
5,2 Intel Core 2 Duo [2 GHz] (Early 2009) my onboard speakers worked out of the
box. But when I plugged in my headphones, that normally work great under Mac OS
and Windows on the same machine, I noticed that I could not get any sound out
of them.

* What exactly did you do (or not do) that was effective (or ineffective)?
I checked all mute options and searched for a solution for a whole week - today
I've found this solution and would like to share it with the community.
I plugged in my headphones -> expected to be able to hear audio.

* What was the outcome of this action?
I did not hear anything, even after checking all alsamixer, gnome-alsamixer and
pulseaudio settings.

* What outcome did you expect instead?
I would have expected to be able to use my headphones to listen to music,
videos etc.


Thank you for keeping this amazing opensource project alive!
