Abit NF7-S: Sound blown?

[eldren]

Harvested together a couple of nice components for my brother's new computer (Including an AIUHB), based on the NF7-S. It was working all perfectly for the first few days.

My brother considers himself a musician, and as such, likes to record what he plays on his guitar onto his PC. So, he plugged a cable from his mini-amp's headphone/lineout jack into his microphone jack on the frontpanel of the case. Since then, not a sound has come from the computer's speakers. Not the frontpanel, not the jacks at the back, nothing. Reinstalled drivers, set the onboard audio off and then on again in the BIOS, nada. Plugging headphones into the frontpanel microphone jack, however, does give a sound spike, indicating that the microphone jack is still being powered. Also, according to Windows, everything still works perfectly, and, apart from the lack of sound, everything else is just fine.

So. Has he somehow blown Soundstorm's audio output? Or is this something anyone's seen before? Help appreciated. Thanks.

He plugged it into the microphone socket ?
Dare i ask how loud it was set to on the amp ?

There is a good chance it is dead if you haven't messed with anything else, and it happened after this incident I'm afraid

I've killed a nForce 2 sound chip by wiring up the mic socket to an already amplified source.

That's what the line-in is for

Not loud at all. Putting headphones into the lineout, it was reasonably quiet. In addition, within the Windows volume control, microphone boost was turned off.

Thats software though. Unlicking a box wont magicaly change the incoming voltage is being fed
Caged is correct, thats what the line-in is for. If its just stoped working after you have done that, (ie. no other system changes, software of hardware) then id say its dead im afraid
