7559 Headphone Jack

Did you ask your dog? ;)

Make sure and check the wiring on the headset, the dog may have damaged it.

Do you see any physical damage to the audio port?

@KAV1983"Is it possible to replace it?"

Yes. This is the circuit board with the audio port. Much easier to replace the board than just the jack.

Thanks for the replies! Unfortunately I have tried several different headsets and headphones with the same result. I do not see any damage on the jacks or ports however it definitely feels...looser. But that could also be my mind playing tricks on me. When I plug the headphones in I do not get the pop up asking me what I plugged in. When I try to open the Dell Audio App on the laptop nothing happens, it won't even start up.

Replacing the entire board seems pretty complicated, a little above my skill level. I have read other threads on here that talk about rolling back the drivers or re-installing them. I did try to reinstall them once but I may try that again. What are the chances the headphones being ripped out resulted in a software v hardware failure? I feel like a hardware failure is more likely, but I seem to be getting similar "symptoms" as other users with audio software issues.

Thanks,

KAV

It is hard for me to imagine a dog being able to break the port on the system.  But I suppose it could happen.

The link Jim provided shows the replacement card and details.  It appears that card plugs into the mainboard with a connector on the bottom.  If there was enough force, possibly the connector on your current card could have been dislodged or compromised in some manner.

If it was me and I was thinking about replacing a card like that, I would want to see first if I could get to the card to verify its configuration and effect the replacement, before I ordered a new one.  While doing that I would make sure the current card was fully inserted into the connector on the main board.  You should be able to use something like the eraser end of a pencil to apply pressure to reseat.   If you were to notice a physical problem with the board and it would not reseat then you have confirmed your situation, even if you send it in for repair.

Using the Service Manual for the system should allow you to see where the card is located and what has to be done to replace it.

If you want to try the driver route, I like to download the current driver then go offline.  Use Device Manger to uninstall the sound device and check the box to remove all drivers.  Once that finished, click on the icon to check for PnP devices to see if a Realtek driver comes back.  If it does, uninstall again.  Once you have a basic HD driver, then install the downloaded driver, reboot and then go back online.

TL;DR: Same thing happened to me, and you can fix it by bending the contact leads inside the headphone jack back into place.

I had almost exactly the same thing just happen to my 7559, and I was able to fix it without replacing any parts. First, my toddler grabbed my earbud cord and pulled it out very roughly and at a downward angle, afterwards the headphone jack felt "loose" and did not trigger the auto-detect when I plugged my earbuds back in.

To fix the issue, I used the service manual to dissemble my 7559 and remove the I/O circuit board containing the headphone jack and the USB ports. At that point, I used a set of very pointy tweezers to press on the outside of each of the four contact leads inside the jack to bend them in towards the area where the plug is inserted (one on top front, one a little further in on the left, one beyond that on the right, and one accessed through the back of the jack). The plug felt much more firm after this, so I reassembled my computer and everything worked fine. 

I figured that the rough removal of the cord bent one of the leads out of place, causing the loose feeling and preventing the computer from recognizing the cord was plugged in. Bending them back into place fixed the problem. Hope this helps.
