HP laptop speaker no sound: but can hear through headset

millionpyong · #1 Sep 21, 2007, 06:04 PM

I have an HP laptop. The speaker has been working with no problem for 2 years. Suddenly today, the speaker stopped working. The sound card is OK because I can hear sound through my headphone. Did some quick research and read something about my laptop not being able to not properly sense the headphone jack plugged in or out... Has anyone of you experienced or fixed this problem? Any help is appreciated.

Unless the designs have changed significantly the internal speakers are deactivated by a mechanical switch that is part of the headphone jack. A failure of the internal speaker(s) to reactivate after the headset is unplugged stands a good chance of being a hardware fault in the headphone jack. Without examining the interior of the computer it would be difficult to determine if the fault is the result of the contact being broken OR of the contact being bent to the point that the contact doesn't close when the plug is withdrawn from the jack.

There could be many problems with your laptop. One may be that dust or other material could have collected around it and restricted access to it. Though this is most likely not the problem. I suspect it is a problem with download and installations. What have you downloaded or installed recently? Have their been any error messages or other problems on your computer? What other problems have you had with this computer? All of these could effect what comes out of the speakers.

Hi Robertva and Will00. Thanks for your answers. I haven't had the time to take my laptop to a shop or do it myself yet, so haven't yet verified that Robertva's solution is the right one. My 3-year-old son had pushed one of the headphone jack too far in, so it may well have caused the problem. It's been a while since he had done that, though.

As for the response to Will00's answer, my Norton anti-virus program has been giving me an error a few times lately. It said there was some kind of error to the program and that I had to delete it and reinstall it. I ignored it (I probably shouldn't have... but didn't have time...) and the error went away. I was thinking that had nothing to do with the speaker problem... could it?

I think it's time for your laptop service, Take it in for dusting and all in all clean up. This might have been caused by anything but You can only be sure when you open it up...

I have an HP dv6000 series laptop and I am having the same problem.

I can hear sound when plugged into either headphone jack (theres a regular one and the SPDIF) just not out of the speakers.

Ive run countless tests to see if it was a software problem or a driver problem but one of my friends works as a computer technician and hes going to take a look at it but trust me you are not the only person so experience this.

I accidentally plugged in a Ipod video cable (Ipod video 1/8" jack to red yellow and white RCA plugs)

Well when unplugging it, I noticed the sound didnt come back to the speakers as it always did before.

I am going to get this serviced soon and I will make an update as soon as I find out whats wrong.

I tried to open up my laptop to see if I could see a problem but Its too difficult to get to the jacks without really getting into it.

verman,

i am having the same speaker problem with my HP dv6000 not too long ago. Was yours fixed? If so, what exactly was done?

I appreciate if you could help me out before sending my laptop to HP service shops. Thanks in advance.

The headphone input jack is stuck, there is a small switch inside the jack which shuts off the speakers when headphones are plugged in. When the headphones are pulled out, the speakers turn on again.

The thing you have to do is figure out which headphone jack you were using when you noticed this(im assuming you have 2 like mine).

My problem was that my girlfriend put an iPod video cable into my headphone jack to connect it to our stereo. It fits the hack but instead of a stereo 1/8" plug with 2 sections, it has 3 which makes it slightly longer which is what stuck the internal switch inside the jack and disabled the speakers.

Rather than bringing my computer to get fixed, I just took a pair of headphones and inserted them into the jack repeatedly, at different speeds. Mostly what worked was putting it in and pulling it out rather quickly. have a song playing looped while you do it so that you can tell if it worked or not. It will take some time and patience.

I opened my laptop to try and remove the faulty jack but it was so buried in there that I had no chance at doing it successfully.

Since I "fixed mine" I havent had a problem with it ever since. Only my battery died 13months after I bought my computer....go figure, not 12 which would have been within the warranty, stupid HP.

Also, get some canned air and spray it in the jack making sure not to shoot out the chemical. This might remove any dust/debirs or anything that might be in said jack.

OK so i am stupid and got mad with this switch thing so i open'd up my laptop and just took out the whole headphone jack there is nothing to put head phones in... there is no longer sound, is there any thing i can install or uninstall to just make it play out of the speakers and not go to the input?

This is a mechanical switch inside the headphone jack, it is not a "software" detection sensor or anything. What happens is that when your headphones plug in, this switch "routes" the sound through the headphones instead.

You comment would be like if your keyboard buttons were stuck and trying to fix it with a software download, it just wouldnt work because one is SOFTware and the other HARDware
