This is my step daughters laptop. sadly she lent it to her cousin who downloaded x rated material with it! We took it to a repair shop who re-installed everything.
Before the re-install the internal mic was present and definitely working! Checked in Playback Devices and can see a mic icon , but it seems to be a jack for an external mic? Can't see anything else in there? Also checked in Device manager and can the same thing. Can anyone help please?

I would go to the laptop's manufacturer website and download the audio drivers for the laptop. There is usually a small description for each driver so you can find the one you need. Or you can take it back to the shop since you paid them already to get it in working condition and they clearly didn't test every component to ensure it was working.
