Bug Description

Hiya,

The title pretty much says it. When I insert headphones into the jack on my laptop, the external speakers are not muted and the headphones are not activated. I have to lower the master volume to the minimum level (not 0 as this mutes all outputs) and raise the headphone volume. This should be done automatically.

  - Jack sense should work
  - Adjusting the master volume should also adjust the headphone volume (providing that the speakers are correctly muted...)

Regards,
Iain

This is similar to bug 437150, but is about a slightly different module. dtchen asked me to file a new bug and triage it to Linux, so that I have done.

affects: alsa-driver (Ubuntu) → linux (Ubuntu)

I've developed a patch against alsa-driver-1.0.22.1 which should fix this (which I've attached to this bug), which you can test as follows:

First make sure you don't have any versions of linux-backports-modules-alsa installed:

apt-cache --names-only search linux-backports-modules-alsa | cut -f 1 -d ' ' | xargs sudo apt-get remove --purge

Now download alsa driver source and the patch, and compile and install a patched version of the driver:

cd ~
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.22.1.tar.bz2
wget http://dl.dropbox.com/u/174251/alsa-driver-1.0.22.1-mb5.patch
tar xjf alsa-driver-1.0.22.1.tar.bz2
patch -p0 < alsa-driver-1.0.22.1-mb5.patch
cd alsa-driver-1.0.22.1
./configure
make
sudo make install

Now you need to reboot your machine. If this works I'll push the patch upstream and hopefully we can get it applied to linux-backports-modules-alsa as well.

This bug is almost the same as bug 488103 which is about the MacBook Pro 5,1. Should it be marked as a duplicate?
Also, the same patch from Alex Murray is posted there, and fixes the issue for me on my MacBook 5,1.

That bug conflates a lot of different issues, whereas this one is rather specific to jack sense on one particular model. It should be kept open and unduped until the problems the report describes are fixed for the model it refers to.

@Iain - can you confirm if the patch fixes this for you - it should, and so this bug should be marked as such.

I will soon. But that won't affect the bug status. It should still be upstreamed and uploaded to Ubuntu as appropriate if indeed it is a good fix.

I think it's working now on Lucid. Please, someone else confirm.
