Hi, Many thanks, Ive actually fixed it.
Here is one, as daft as it sounds.
There are two High Definition Audio Devices under Sounds & Game controllers in the Device Manager.
I only uninstalled the one with the Exlamation mark before and also only uninstalled the
driver via Properties.
When i deleted the other one as well second time round (There is obviously a link for both devices) it re-booted and worked perfectly.
It might be as s imple as making sure all adio devices are removed /uninstalled and re-boot.
Great Result, Thx
