    Hi all,
    I've recently got a T420 4180A32 (Conexant CX20672) and the headphone jack doesn't work under Windows 7. It works when I boot (natively) into Ubuntu, but obviously when I run a Virtual Machine into Ubuntu through Windows, it doesn't work either.

    I have:

    - Uninstalled and reinstalled the driver version that came installed.
    - Installed, Uninstalled and reinstalled a newer driver version.
    - Uninstalled the old driver and installed the new one.
    - Reverted to using the generic High Definition Audio driver. The speakers work fine but again, headphone jack doesn't.
    - Established that it obviously isn't a hardware problem.
    - Uninstalled then reinstalled DirectX
    - Tried various headphones on the off chance that they were the problem. They weren't.

    I haven't:

    - Done a full reinstall of windows 7 (although I might)
    - Tried Windows 8, although again, I might as I have an unused licence for it and I really want my headphones to work.

    That's about all the info I can give. Besides this problem, the laptop runs great!

    Any help would be appreciated.
    Thanks
