Thanks for the tip, i wasn’t sure if it would be part of the intel speakers driver or a separate one so that is useful. I rolled back the driver (had to do this in safe mode) and i still i have no microphone input. I will have to keep fiddling around i guess. Annoyingly i also have tried uninstalling the driver so i can manually install the one that is in the downloads on this website, but it comes straight back in device manager.
I will report back if i ever get it working in case anyone else has the issue.
EDIT SOLVED: thanks for the tip for using driver booster, it found that their was a new driver for intel sound, updated it and it worked!
