What kind of sound card to you have and where are you plugging in the headphones? The jack commonly found in front of a CD-ROM has nothing to do with the computer's sound output. If however, you are using the panel from a SB-Live, the headphones automatically muting the speakers is a software setting speciffic to the driver. The only computer I have that has one of those is over an hour away from me and not available from the Internet, and I can't remember where to find it off the top of my head... sorry. If this is your case, I'll try to look it up.

I have installed kubuntu on my laptop, it is HP (Compaq nc8230).

I plugged the headphone in the laptop

Usually, inserting headphones (or anything the right size) into the headphone jack would physically disconnect the electrical path to the speakers and redirect them to the headphones. Evidently, this laptop doesn't do that, but I'd still be surprised to find that the headphone/speaker switch was software driven.

Actually, that is the case. According to this thread, You have to manually check the headphone sense box...

Well, not sure if this will be helpful because I am guessing most of you have done this already and I am new to this whole Linux thing, but I was also having the same problem with my HP Compaq nc8230. Turns out, Ubuntu didn't have the "switch" enabled by default to recognize the headphones when I plug them in to mute the main speakers. To fix it, opened up the Volume Control for the Intel ICH6 driver, click the switches tab, and put a check mark next to Headphone Jack Sense, and that did the trick. Like I said, not sure how helpful this would be but here you go.

Yeah, I've also found out that manually disabling the laptop speakers does the trick. In my case, turning off "external amplifiers" from Kmix (I use Kubuntu) does the job.

If that doesn't work or you can't find this option, there's the manual edit of a config file method; open a terminal and do the following:

sudo nano /etc/modprobe.d/alsa-base

Add/edit the following line:
options snd-hda-intel model=lenovo

Save the file (Ctrl+x , y)

Restart the laptop. See what happens!
