Hit screwdriver on motherboard, no more sound

Hi guys, well yeah, I accidentally the bottom part of my motherboard of my laptop under the mouse buttons, not sure what I hit as I see no scratches but my sound no longer works. I have reset bios and reinstalled drivers to see if that would reset it or something but the problem is still there. Any ideas on if I have short circuited it and if there is a repair?

The laptop is an Acer aspire 5630. Running Win 7 if that matters

thanks for your time
