So here is what happened.  My roomate put his headphone in his ear. He as one of those kind that you put in your ear.  When he does that he is zapped my some juiced from the sound card or actually out the controller unit.  His sound goes out so he decides to reboot.  That did not help so I told him to reset the sound card.  He reset the card and it is working just fine now.  I was just wondering what happened?  Has anyone ever had this happen to them?

I suspect the "juice" was static and it either caused a CMOS latchup or scrambled logic registers on the sound card. The former is often fatal for the sound card so I suspect the latter. A reboot should clear scrambled registers unless the registers involved are nonvolatile. A CMOS latchup requires a power down but this could occure with on board power save hardware on the sound card. The static could have caused latent damage that may mean a premature failure some time in the future. The sound could could also have some form of circuit breaker that tripped.
