No Audio after installing Windows 7

[izaki]

I have installed Windows 7 Ultimate on my computer after reformatting it.
The installation is successful but there is no Audio.
When i click on the properties of the Sound & Audio,
the error says: "Cannot start this device. Code 10".

I have tried to update it through Windows update, but there is no update for the audio driver,
it always says 'Your Audio Driver is Up to Date'.

I have manually tried to download and install the Audio Realtek HD sound Driver,
Still does not work.

Please Help!!

Let's make sure that your playback devices are enabled.

Right-click the speaker icon on your taskbar > Select 'Playback Devices'
In the empty space, Right-click and select both 'Show Disconnected/Disabled Devices'
Do you see icons for your speakers and headphones now? You may need to enable both of these.


You can also try the troubleshooter to discover any connection issues that may exist, instructions are below:


Click 'Start' > Select 'Control Panel'
Type troubleshooting in the top-right search field > Select 'Troubleshooting'
Click 'Hardware and Sound' > Select 'Playing Audio'

Yes i have done that.
I click on troubleshoot and its says "HD realtek audio device Not Fixed".
The playback device is on, i tried playing songs on it through my mobile phone,
and it is working, but when i attach it to my PC there is no sound, no nothing.

and when i click on audio devices it says "No audio device connected."
it was working fine before i formatted my drive and re-installed win7.

I seriously have no idea what went wrong.
