Probably both voltage and current, but at that voltage it wouldn't matter
anyway (the power dissipation would be too large). The line in of my
soundcard also got fried while testing oscope on a computer motherboard at
12V, the rest of the soundcard is OK. It later turned out it was a 15A
line. Guess I have a penchant for the volatile!
