Windows 10 (LINX 10 Tablet) No Audio Output Devices?

So i've had a used LINX 10 Tablet for a few weeks now and it's been working fine untill now.
Windows appears to have "lost" my audio drivers and simply doesn't recognize any audio devices connected, not even it's internal speakers.

I've tried to reinstall windows 10, reinstall the chipset drivers, update the drivers and have yet to find a way to get the audio back, my current work around is to plug in a USB AMP acting as a soundcard (Creative 0202 USB).

Anyone got any bright ideas as to why the audio appears to have just disappeared?
