Help required on the terminal

Hello everybody,
I didn't wrote in english for many years... I hope you will understand my terrible language

I have a macbook pro 15' with snow leopard.
I connected a mini-jack headphones in it in the usual port and the mini-jack went broken in the hole. I have to bring my mac to the technique support to fix this. (they have to open the whole stuff and change the sound card because the broken piece cannot be taken out)

Now my computer thinks that I have headphones connected. It want not give me sound over the normal speakers.

My question on the terminal is the following:

I'm wondering if there would be terminal command to have the sound given by the speakers with "headphones" connetced, because I didn't found anything in the prefs to do this?

Thank you,

Try some of the techniques found here:

Thank you for the fast reply and for the link.

My problem is that there is only a very small part of the plug that is stucked at the very end of the jack.

It is too far away to glue it or do something like that...
The technician couldn't do it either.

My problem is that I habe to finish a music job (i'm musician). And only after that I will be able to give my computer to fix this...
So temporary terminal solution would be great for me...

Looks like SoundSource might do the job for you.

Do you think it will do that while the hardware is forcing the software to think that there is a device in there.... being a 15" with separate input/output?

I thought of apps like this for the 13", but the 15" got me wondering.

Now I got thinking a bit more, and I think 13" or 15" it should work.

Soundsource uses the hardware prefs.
Doesn't work... :-(

Bummer.... Ok, only other option I can think of is getting to a jeweller ASAP who may be able to get it out.
Otherwise, getting your hands on a friend's Mac if you can (just to work on your project).
