Windows edition: Windows 7 Ultimate Service Pack 1
Model: HP Elitebook 8440p
Processor: Intel(R) Core(TM) i5 CPU M520 @2.40GHz
Installed Memory (RAM): 2.00 GB (1.86 GB Usable)
System Type: 64 - bit Operating System
At first my laptop was not able to detect earphones that I plug in so I decided to install a driver from HP for my laptop. I couldn't find one specifically for Windows 7 Ultimate so I downloaded the one for Windows 7 Professional. Ever since I installed the driver, the earphones work fine now but the laptop speakers does not work. When I click the volume icon in the notification area and I play music or video it indicates that there is sound playing. I tried reinstalling the driver but it still doesn't work.
Hoping you can help me with this one. Thank you in advance!

Here are a couple of thing to check.
1. Shutdown the notebook. Tap away at the esc key as soon as you start the notebook to enter the Start-up Menu, then select f10 to enter the Bios Menu. Under the System configuration tab, expand 'Built in Device Options' and check that both 'Audio Device' & 'External Speakers' are both selected - save any change before exiting.
2, If the bios shows the above options are already checked, try the following.
Download the IDT HD Audio installer on the link below and save it to your Downloads folder.
When done, hold down the Windows key and press R
Into the Run window, type devmgmt.msc and hit enter.
In Device Manager, expand 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, download and reinstall the Chipset driver on the following link.
When the Chipset reinstallation has completed, shutdown 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.
When windows has reloaded, open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, restart the notebook and let windows fully load for a few minutes before checking.
