No sound from internal speaker Hp laptop

Hey everyone its my first time posting here.. and I do not speak English very well but I know you guys can help me. I bought a dv6000 hp laptop with windows Xp in the USA. One day of those I was listening to music trough my earphone and after I unplugged it I could not hear any sound from my internal speaker. Only from the headset. Ive searched everywhere on internet and I could not find any solution to my problem and I would be glad if anyone could help me.

    I've already checked the sound settings and reinstalled the audio driver and update the bios. I had this problem before  and I system recovered my pc. The sound came back but I used the earphone again and unplugged it and the same thing happened so I recovered the system one more time and it did not solve my problem.

    I have no problem with my powerbutton  and the quickplay touchbuttons work fine.

    I'm sorry but I did not understand what you meant with "But since this happend after you used the audio pass through board, that is the most likely cause. If you are comforteble opening the notebook, you can check this by disconnecting it. If the sound comes back on the internal speakers after disconecting it, it will need to be replaced."

    Disconnect what?

    Thank you so much for your help!

I recomend you check the soundsettings for output devices in the controlpannel first, and try reinstalling the audio driver and updating the BIOS. If you want to be 100% sure its not a software problem you can also a full system recovery. You can start it by pressing F11 at the HP logo during boot.

But since this happend after you used the audio pass through board, that is the most likely cause. If you are comforteble opening the notebook, you can check this by disconnecting it. If the sound comes back on the internal speakers after disconecting it, it will need to be replaced.

Else, if the powerbutton does not light up(it should when you turn on the unit) it is a defectice PBB cable. But even if it lights up it doesnt rule out that the cable is defective. If the quickplay touchbuttons are sett to give a beep when pushed, you should check if they still do. if not it strengthens the probability of the defective cable.

This can also be a defective mainboard. But this is a very rare mainboard problem on these models.

If the unit is out of warranty and you want to replace the parts yourself, I can provide you partnumbers. But i will need the modelnummber form under the unit. It should be written on a small whtie lable and look something like this AA111BB#CCC.

    The "audio passthrough board" also known as "Audio/IR board" is the circuit board in front of the mainboard with the audio connectors.

    The problem might be related to something shorting in this board. Causing the unit to think there is a headsett connected, and disabling the speakers. So disconnecting this board would stop the shorting, and the unit would act as if no headsett is connected and enable the speakers

    Here is the servicemanual. If you go to page 3.2 you can se it. Its part number 15. I dont know if this is the exact same model as you have, so I dont know if the partnumbers will fit your unit.

My HP 610 laptop's inbuild speaker is not working,but with the external speaker it is working.I want to know the price of HP compaq 610 inbuild speaker.

Try the following steps:
Open your laptop carefully (look out for fragile ribbon cables) !
Check for a broken wire going to the internal speaker.
Check for a faulty contact at the audio output jack (these things have a contact which disconnects the internal speaker when a plug is connected).
Temporarily connect any speaker in the place of the internal speaker.
If the problem is still the internal speaker, remove it and go to any good audio components shop and buy an equivalent speaker.
Hope this helps.

I have no sound on my HP Pavillion laptop

I had the same problem, but now its solved!

Brieftly speaking, my internal speaker stopped producing sound, but when I plug earphones in, there is sound in the earphones.

Just plug in-and-out ur earphones several times (it took me 5 tries) and voila internal speakers work again!

I think there is a mechanical sensor inside the sound output (plug for the earphone) so that once it senses a plug getting in, it shuts internal speaker.

Maybe the mechanical sensor was jammed (spring problem i guess) and it still believe that u have ur earphones plugged-in. "Clogging" the hole for the earphones would allow the spring to spring back to initial position...

Hope it helps
