Hi Guys, I know this may sound odd but with the main laptop being sent to service the original hard drive has been placed in another laptop slightly lower spec.
Now everything is working and device manager tells me that every hard ware is installed correctly( i have loaded the drivers where necessary).
Everything work BUT the audio.
in the hardware it shows that it's there but on the audio control it has cross on it and tells me that "no speakers or headphones plugged in".
I have tried reinstall the driver with vendor (RealTek) driver but with no luck, remove the device and drivers to see if windows default driver work but no luck, BIOS has no setting to enable/disable onboard audio, I have tested the hardware with running linux on usb stick and confirmed that audio device is still functional.
I have windows 7 x64 installed on this hard drive, I have confirmed that this model supports 64bit OS as it has drivers for Vista.
If anyone has any clue to fixing this other then reinstalling the OS please let me know.
