Windows 7: No sound from speakers or headphones, computer shows them as unplugged

Hello.

The audio from my computer completely went dead when I turned it on. The speaker icon shows the symbol with the 'X' on it and after clicking it and going through the troubleshooter it can detect no problem. I tried updating the drivers through the HP website, and uninstall/reinstalled them but it still doesn't work. I even tried rolling back the computer to a restore point but that didn't work either.

The speakers are built into my monitor and is connected through a normal audio jack (not HDMI). I normally use my headphones through a jack built into the front of the tower.

My computer is a hp Pavillion Elite m9400f, Windows 7 Ultimate 64X (It also has a ATI HD Radeon 5770 graphics card; but I'm not sure if it's relevant to what might be causing this problem)



Any and all help would be much appreciated. Thanks!

You can try going to your device manager. Right click the audio device and select disable. Wait a minute, then right click again and select enable. See if this works for you.

Hi Lemur,

I tried as you suggested, but no luck.
