    No sound after upgrading to Windows 8 Pro


    I upgraded to Windows 8 Pro two days back and I am coming across this problem.

    When the W8 Pro started for the first time, there was sound. I didn't have to install any driver for it. But the very next day when I started my laptop, there was no sound and at the right hand side of the taskbar there is a Speaker icon with a red cross over it which says "No Audio Output device is installed".

    I tried a System restore that didn't solve the problem. Downloaded R270 driver for Windows 8 from Realtek. Funny thing is that when the installation got completed and it asked for a reboot, sound came afterwards. But that too was till the time when I did not switch off the system. Next day, no sound as usual.

    I tried different "Fix it" from Microsoft but they didn't do anything.

    I ain't sure if I should do the "Troubleshoot compatibility" installation of the sound driver.

    Please help guys.
    P.S. This Laptop came with Windows Vista, then I upgraded to Windows 7 and now this Windows 8 Pro.

    I installed the latest driver(6.0.1.5449) from the link in the Compatibility mode but still there is no sound.

    In the device manager, I could not find the Sound option but when I chose the "View Hidden Devices", there was a Sound device.
