strange speaker problem on a macbook 2,1


dual boot: ubuntu 11.1, max osx
macbook 2,1. extra ram is the only difference.
My external speakers don't make noise, but the onboard speakers work. In fact they work for the first time since I started using this computer because of an existing problem. There is a problem when running OSX where the on board speakers don't work because it is constantly recognizing an external connection even though there is nothing there. I tried to fix it but there is no current knowledge on how to fix it other than using a pin to wiggle around in the connection. The result is that it always has a red light on in the speaker jack, but nothing is connected.
When I installed Ubuntu I was able to use the internal speakers just fine, but when I went to use external speakers they did nothing. Does anyone have any information on this problem, I have looked all over for a solution. thanks.

P.S. someone told me to check alsa mixer to see if they are muted but I checked and I dont think they are. maybe a readout from Alsa mixer would help but Im not sure how to do that.

Are you sure that you're MAC do have a connection for a external speaker ?
Or are you using the headphone connection for the external speaker ?
Or maybe the digital or analog line out for audio ?
This is important to know to solve you're problem in Ubuntu with connection you are using .
The command in OS X system_profiler will detect among others what kind of audio connection you're MAC do have .
In OS X System Preferences give you the option to select you internal speaker also Itunes give you that option .

00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)

is the lspci response about my audio jack. It shows a headphone symbol on the jack. One easy fix I can think of is to get a usb to audio jack converter but it isnt the solution im looking for.

Did you have a analog and digital out yes or no ?
If yes the analog out can be the input for a audio amplifier and loudspeaker box .
For instance from Logitech .
Using analog out that is the way I use it on my linux box .
It works perfect .
The digital out should be connected to a DAC + Audio amplifier + loudspeakers .
Most Apple people use APPLE TV or Airport Extreme to connect to external speakers .
Here is a article to trick Apple TV to run under linux http://www.chriscarey.com/wordpress/...running-linux/
As it a article from 2010 it is about Apple TV 1 .
It might be possible to buy it second hand .
If it works with Apple TV 2 I do not know .
But both Apple Tv and Airport Extreme needs a audio amplifier

it is analog out

I was looking to fix the problem itself rather than work around it if it is possible. but I appreciate the advice.
