First Try Using Sound Troubleshooter
It usually fixes the most common problems very fast. If that cannot fix the problem. Follow the steps below.
First unplug your headphone. Right click your speaker icon in the notifications area and select playback devices. Check to see your speaker/headphone is set as the default playback device.If it or If not set your speaker as the default playback device and the default communications device.Then plug your headphone and reopen the playback devices window again to see if the headphone device shows up.
If It Shows Up
Then set that as the default playback if it shows up.
Check your headphones now. It should be working.
If still no sound, double click the headphone which you just made the default playback device. A dialog box should open. Go to the levels tab and check the volume or mute. If that is fixed and it still doesn't work go to advanced tab and click on the test button. You should hear two 3 sequence tones through you headphones.
If It Does Not Show Up
If it does not show up just double-click your default playback device.Go to the levels tab and check the volume or mute. If that is fixed and it still doesn't work go to advanced tab and click on the test button. You should hear two 3 sequence tones through you headphones.
Still No Sound ?
If you still do not hear any sound through your headphones then it might be something wrong with your drivers.
Go to device manager by right clicking your start menu. Then go to Audio Inputs And Outputs. From there you should see a list very similar to your playback devices in your sound control. Right click your device ( in my case 'speakers') and click on 'Update Driver Software' followed by 'Search automatically for updated driver software'. If a new update is found install It. Then do the above steps again.
If it does not work for Audio Inputs And Outputs, try doing the same for your soundcard driver from 'Sound,video and game controllers'. In your case I'm assuming it is 'High Definition Audio Driver'.
Even Further Steps
You might be having more that one driver software. Uninstall any third party audio or sound drivers. This is usually a rare case. Do not uninstall the audio driver that comes with your processor (in your case 'Intel Audio'). Then restart your P.C and follow the steps at the beginning to set as default playback. It should work this time. Do not do the update for the drivers this time around. This will cause the drivers to get re-installed.
