Sound no longer working

Had a party last weekend and for some reason the built-in soundcard on my motherboard stopped working. The computer was untouched under the desk the whole night so I don’t think it’s related.

Either way, I can’t seem to figure out how to get them working again. Theres nothing wrong with the speakers and I tried reinstalling the drivers. Don’t know what else I can do.

Time to buy a proper soundcard?

Thanks =).
