Latitude D620

I just recently got a new laptop at work (a Latitude D620) and when headphones are plugged in to the headphone jack, the system still plays music through the main speakers. Nothing is heard in the headphones. I've tried several things I found online with no luck, but was wondering if anyone else had run into a solution for this.

Relevant data:

Code:

The alsa mixer contains no settings for this that I could find.

Any suggestions?

I can only suggest a couple of very basic things: are you certain that the headphones are completely plugged in? Obviously, once the headphones are plugged in the speakers should be muted. That said, considering that the laptop is brand new, the speakers are working correctly, but the headphones are silent when you plug them in, there's definitely the possibility that your machine's headphone jack is defective.

The headphones do work (tested on multiple devices) and are plugged in fully. I've also tried a different set of headphones with the same results. I do have to consider a defective jack, but I'll try booting into Windows later to test that.

Thanks for the input!

I was wondering if you ever got your problem solved? I am running into the same problem as well. My Headphones/jack works perfectly in windows, but not in linux(kubuntu). I even went so far to compile the new version of alsa, and it still plays from the speakers

No, I haven't gotten it solved as of yet. I'm contemplating trying to upgrade to a new kernel from source, in hopes that drivers in something like 2.6.17 might work better.

i also tried that, but i might have done things wrong *still kind of like a newbie*, so if you do try to compile from source, please let me know
