macbook 3.1: Internal speakers don't silence when headphone socket is used from boot.

I have a similar problem on a macbook 3.1 with ubuntu 8.04 beta. if my headphones are plugged into when the computer is turned on then the sound comes out the speakers instead of headphones. If i unplug the headphones and plug them back in everything works as it should.

ramaboo, you are absolutely right. That is the actual behaviour I am getting. I did not look into this thoroughly enough. I am going to change the bug title and description. I am using Gutsy by the way.

Please execute the alsa-info.sh script referenced from https://wiki.ubuntu.com/DebuggingSoundProblems and attach the URL here.

I can confirm this issue also exists on my Macbook Pro 4,1 running Intrepid. Here's the requested information: http://www.alsa-project.org/db/?f=3e98928842d58d7406cd2458ada92aa525c294d1

I'm reopening the bug.

Alex, this should be fixed for you in jaunty. If you are running jaunty, or are willing to try the latest jaunty alpha to make sure of this, could you please reply back stating whether things work or otherwise?

Thanks.

I'm running the latest version of Jaunty and still have this problem.

Thanks.

I can confirm, I am also experiencing the same problem. The results of alsa-info.sh can be viewed at:

I am able to compile / test patches if needed.

Hi munk3h,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . Please then run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 205059

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I experienced exact the same bug on Lenovo N200, with all versions of ubuntu, opensuse, fedora, and few others.
Only distro that doesn't have that bug is Sabayon (4.2)! I'm uploading alsa-info.sh generated on it, hope that will help. I have Sabayon currently installed so I can run more test/scripts/etc, just tell me what to do.
