No sound coming from laptop.

By raptormoonx ·
I have a HP Pavilion zv5000t laptop. For whatever reason, I cannot get any sound to come from the unit. I've tried System Restore, uninstalling/reinstalling the driver, updating the system BIOS (already updated to latest version), updating the driver (already updated to latest version), turning on the Audio Service via Windows XP Pro, but nothing's worked. I've stopped short of reinstalling Windows since it recognizes that drivers are installed. Could the card be burned out or loose? And no, the laptop IS NOT on mute. >_<;; Is there any way to find out or fix it myself? Any help would be greatly appreciated. Thanks!

Have you tried plugging in a set of headphones to see if they work?

If they work, it may be as simple as a problem with the switch in the headphone jack. Of course, the problem is that you would have to replace the headphone jack.

It also could be a wire off that runs to the speakers. Or, the audio output drivers are damaged.

If the audio output drivers are damaged, device manager and Windows would still think you had a working sound device as they only look at the digital side of the audio system.

Have you looked at the sound device in the Control Panel

by OH Smeg Moderator In reply to No sound coming from lapt ...

Quite often particularly with Games this can be altered so look in the Control Panel under Classic View to Sounds & Audio Devices then click on the Audio Tab and see if your sound device is listed in the Box. If it is not click on the drop down arrow and select it.

You can also look in the BIOS to see if the Sound is turned on there or if it has been set to Disabled. It needs to be Enabled in the BIOS and you need to Save the Changes when you Exit the BIOS.

The last possibility is the actual Jack that you plug external Speakers or Headphones into look at these and see if there is anything stuck in any of them. These have a switch in them to disable the NB's Sound and Mic if there is a plug inserted into the Socket. Sometimes these can get filled up with junk and disable the NB's internal speakers.

If none of that has any effect it needs to be returned to a Authorized HP Service Agent for repairs.

Headphones work while speakers don't

I just tried using headphones and it works with them. Can't get any sound to come out of the speakers, though. >_< It's not a big deal since I have to use headphones at work, but it is a bit scary not knowing what's wrong. ^^;; I am not much of a techie person. I'm more of a multimedia/game design person.

Headphone Jack has a broken part in it or it's stuck in the open position which prevents the sound being feed to the internal speakers.

If you turn it off and give it a solid thump it may clear the problem or it may not just don't do that while it's running or you could trash the HDD.

Another possibility is that the Lead to the Internal Speakers has become disconnected or broken. But if it was making a bet and knowing that headphones are used regularly I would say it's the Socket that you plug them into being the most likely culprit.

Now as most of these sockets are part of the M'Board and not on a separate plug in card it may require a replacement M'Board to fix. Not really worth it if you regularly use headphones though as if one socket has failed it's very likely that another one will as well. Of course it's always possible to solder in a new socket but you'll need to have someone who knows what they are doing here and with the correct equipment to safely replace the socket.

You could always use a set of external speakers when at home as they plug into the same place as the Headphones are cheap and produce better sounds than the built in speakers. That is what I would be doing as you can get a cheap pair of the Creative Brand for under $20.00 that have a 8 W RMS which is far higher than the NB Speakers and with better Bass Response as well.
