[Bug 205059] Re: macbook 3.1: Internal speakers don't silence when headphone socket is used from boot.

 

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.

I have a MacBook 3,1 and when I connect headphones or speakers to the headphones socket, before booting the laptop, audio comes out of both the headphones and the MacBook's internal speakers. If, the headphones are unplugged and replaced, normal operation is restored.

If I perform the same scenario in OSX leopard, nothing goes wrong. I suppose this means that the function of switching from speakers to headphones is software controlled.
