HP laptop sound not working Windows 7

Be helpful to know what he was doing when they died. He could have shorted out the Ouputs.

yeah i know... think they just stopped working, But like i said i think its a hardware problem with the Sound card because neither the laptop speakers nor the headphone is working but in windows 7 when you open the volume button / mixer your can see that windows is giving output like it is playing sound.

I hate sound issues, getting a call from the music dept always sends a shiver down my spine. What I now do after many a year of hair tearing is start again early on. Id clone the hdd as it is with something like clonezilla so you can restore it. Then Format the sod and re-install windows etc. This will most of the time confirmwhetherits hardware or software.

I had a case last week were one of the recording studio comps stopped playing sound, there were no visable issues with drivers etc. I tried a system restore, reinstalling drivers and nothing. Wiped and started again andeverythingworked fine. Ive seen this a few times now.

If it is Windows Vista or Windows 7, try restarting the Windows Audio* service[s]

With HP as well theres sometimes a bit of software on there to run the volume control etc, its called something "OSD", this may have got un-installed if the guy thought it was some bloatware.

Try Safe mode on the laptop see if that makes any difference

whenever I want to check if hardware is broken I tend to use a linux live cd like ubuntu and use it to check the hardware.

I would check the Soundsettingsand see which device itsusing. I have seen themattemptto use the modem over the sound card.It'swacky.

+1.

You need to first determine whether the hardware is, in fact, working or whether your user had borked Windows is some manner. Using an Ubuntu CD is a great way to check. If it works on the LiveCD, it's a Windows problem.

Also, keep in mind that there are often several different ways to adjust sound on a laptop. Don't trust the user to know about them all and make sure all volume controls are unmuted and turned to max volume. I've been bitten by this in the past.

Next, System Restore is unlikely to correct a major driver issue. After checking the above, try to rollback the audio driver. Windows Update in Windows 7 is light years ahead of XP in terms of properly identifying drivers, but it does occasionally get it wrong.

Finally, try a fresh install - preferably on a spare hard drive. A base Windows 7 load will take less than 20 minutes. Don't forget to check the warranty status, too. If it does end up being hardware, you'll need to replace the motherboard to fix it. This if often not cost-effective for out-of-warranty units.

Tnx guys,

Atleast i have a lead now. Downloading the Fedora live image now and gonna put it on my USB to see if the sound is working in Linux.

I will let you know the results!

That is a rare mode of failure for hardware.

A lot of subtle items can cause issues, like the setting of default sound device.

Just made a live boot with Fedora and the sound is also not working neither trough the headphones or speakers.

guess that means the sound card is broken....

Tnx all for the help and the suggestions!

Hello Martijn,

Sorry to hear that your notebook is experiencing sound issues. The sound issues that I have encountered in the past for a couple of consumer notebooks was not due to a broken sound card. If you would like for me to escalate to our team in the Netherlands, please email me with the product number and product serial number as well as your contact information.

Regards,

Priscilla

Here is ALWAYS my first troublehsooting technique on instances wheresound cards suddenly going 'bad', 'dead' USB ports, and even wireless network cardssuddenly not working - ESPECIALLY on HP laptops and/or desktops[and we have a ton of them].

1] Power down completely

2] If laptop, remove the battery for a full minute [if desktop, pull the power cord for a full minute]. This drains the mobo.

3] Insert the battery [or plug power cord back in]

4] Boot up and login.

I've had this solve SO many HP issues I can't even begin to tell you. And I really don't know why, but I just know it gets results much of the time.

God luck.
