(Wanted) 18 pf and/or 15pf ceramic cap

[Pentium]

There is a component labled 'c1' on the sound card that was bumped off, and as helder has told me, it's essential to get sound to work.
It's a long shot, but I'm gonna try to solder another one into it's place carefully.
I just can't seem to find them anywhere. Help?
