No sound on headphones output

Hello all,

My sister installed Ubuntu on her new laptop and we have run into the following problem.
When we play music the sound comes out right from the speakers, however when we plug in headphones (small stereo jack), there is no sound at all (neither in headphones nor in speakers)!

I am not certain this is a software problem. We have not tried the headphones when the laptop was under Windows (delivered with XP) and we have no way to install Windows back (erased the "backup" partition, there is no cd) just to check.

I have tried everything I could on Ubuntu 6.10 to get sound on headphones but to no avail. In the sound preferences, using ESS, ESD, ALSA or the analog device for sound all work on the speakers but not on the headphones. I also tried every combination of tick/untick in the sound mixer (Alsa mixer).
I finally tried fiddling with the "Function" keys on the keyboard, again without success.

So my question is: Am I missing something important? Do you believe the problem is hardware-related?

The laptop specs are:
Packard Bell MZ35-U-005 , CPU Pentium Dual Core 1.6GHz, RAM 1024MB, HD 80GB, Screen TFT15.4, DVDRW. I had lots of trouble making wifi work but it is now stable.

Thanks in advance for any tip!
Olivier.

This looks more like a hardware issue. Maybe your headphones are broken or the jack itself is a bit broken. In both cases you would not hear sound from neither the speakers nor headphones if headphones are plugged.. I'm not sure what else could it be.. Did you try headphones elsewhere if they work (like on your stereo or TV)? At least then you can eliminate the headphones.

I have no idea, but I guess it would be useful if you told us the type of the soundcard.

I am ashamed to say I completely forgot about this topic.
The computer went back to warranty (with completely wiped HD). They "diagnosed" an "unrepairable problem".
We had to fight to not get another laptop with Vista (XP models are entirely gone now). I will report to see if the same problem comes up ;-)
My apologies for that.
