Laptop sound stopped working

Two days ago my laptop sound stopped working.  My laptop now has no sound at all.

 

Checked sound driver  and device manager, all indicated no problem.  Also, checked sound level, mute, etc and all seem to be okay.

 

So, why don't I have sound?

Hi,

 

Can you post back with the following.

 

1.  The full Model No. and Product No. of the notebook - see Here for a guide on locating this information.

 

2.  The full version of the operating system you are using ( ie Windows 7 64bit ).

Laptop is an HP Pavilion-6 product key [Personal Information Removed]

 

All diagnostic checks & windows updates have not solved problem.

Re: Laptop sound stopped working

Hi,

 

You've posted your Windows activation key, as this is personal information you should edit your last post ( from the Options dropdown box in the top right ) and delete this.

 

You need to post back with either the full Model No. or full Product No. of the notebook - see Here and the full version of the operating system you are using ( ie Windows 7 64bit ) installed on your notebook.

 

Regards,

Re: Laptop sound stopped working

Hi,

 

Try the following.

 

Download the relevant IDT Audio installer on the link below and save it to your Downloads folder.

 

IDT Audio Installer - Windows 7.

 

IDT Audio Installer - Windows 8.

 

When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

 

When complete, shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.

 

Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.

 

Let Windows fully load - it will automatically load an audio driver, but just let this complete.  Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation.  When this has completed, right click the speaker icon in the Taskbar and select Playback Devices.  Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

 

Regards,

 

DP-K

Re: Laptop sound stopped working

 

I am using HP Pavillion DV7-4190us laptop.

 

Windows 7  64 bits

 

I have done everything DP-K suggested, such as, downloading IT Audio Installer following the link provided by DP-K, but still no sound.

 

By the way, I noted that I can listen to videos via my TV set using the HDMI outlet. 

 

Thanks!

Re: Laptop sound stopped working

Hi gwakgira,

 

My previos post was in response to paulrp, so the IDT driver will not be the one you require - I'd suggest trying the following.

 

Open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow thisand then proceed with the uninstall.

 

When complete, restart the notebook.

 

Let Windows fully load - it will automatically load an audio driver, but just let this complete.  Then try using Recovery Manager to reinstall your original IDT Audio Driver - the procedure for using recovery manager to reinstall Software and Drivers is detailed in the document on the link below.

 

Recovery Manager - Windows 7

 

After the reinstallation has completed, restart the notebook again.

 

Regards,

 

DP-K

Re: Laptop sound stopped working

Thanks DP-K for your suggestions.  However, I still was not able to get the sound following your suggestions.  Also, I can't get the Recovery Manager - Window 7 installed properly on my computer.  I download the Recovery Mgr file from the HP site and when I clicked on it ti launch it, it gave me a message something like a "can't launch missing .dll"

 

Help!

 

Thanks!

Re: Laptop sound stopped working

Hi,

 

Ok, we'll try another approach to this - try the following.

 

First of all, download and reinstall the Chipset driver on the link below.

 

Chipset Driver - Windows 7.

 

When this has completed, restart the notebook.

 

Next, download the IDT Audio installer on the link below and save it to your Downloads folder.

 

http://ftp.hp.com/pub/softpaq/sp50501-51000/sp50642.exe

 

When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

 

When this has completed, restart the notebook again.

 

Let Windows fully load - it will automatically load an audio driver, but just let this complete.  Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation.  When this has completed, right click the speaker icon in the Taskbar and select Playback Devices.  Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

 

If you still have no audio, open windows Control Panel, open Administrative Tools and open Services.  Check that the following services are all showing as Status= Started and Start-up Type= Automatic

 

Audio Service

Multimedia Class Scheduler

Windows Audio

Windows Audio Endpoint Builder

 

If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type',  select Automatic and click Apply to save the change.  Then click the Start button.

 

Regards,

 

DP-K
