Here is the problem:
my headphones output jack of laptop is broken, so I can hear sound only in one headphone

Question:
Is there any way through alsa, jack or pulse or any other way to (some OS settings?) to redirect sound output to another normally functioning jack
1. Rear Mic (Color red)
2. Line in (Color blue)
3. I don't know, it has rectangular wave with output defining arrow icon (Color black)

If somebody could help, I would appreciate it a lot the new configuration would need to work already tommorow

Hi there,

I'm afraid there is no such solution, because the function of each jack is determined by the hardware and cannot be changed "just like that" - very much like you cannot re-assign a second water faucet to be a sink when the real sink is blocked. The only exception is with 5.1 or 7.1 sound cards where the function of the audio jacks is really switched depending on the mode (5.1 or stereo only). But even then, hardware has to support that.
There are three solution I can think of:

• Have your Laptop repaired by a professional workshop
• Try to find someone among your friends who is *really* good at handling delicate mechanics and soldering very fine structures, and ask him to try and fix it
• Forget about that built-in sound output and purchase an external USB sound adapter, they're available from about 10 Euros up meanwhile.

None of these suggestions get your machine ready until tomorrow, however.
I'm sorry I don't have any better news for you.

Thanks man,
I had a feeling that hardware will stand in a way
But the advice about external USB sound adapter is great! I hope it will work, how didn't myself thought about that? Thank you! and good luck!
