Max input level of a PC soundcard?

Hello Folks,

What's the max for soundcards? I have read specs of some where it says 22dbu which sounds wrong to me. A Via AC'97 I have seems to max out at 10mV RMS but no clue if that is a standard. There was no data*** on the Via Technologies site. Also, anyone know the "frying level" where it would go kaputt?

The motivation here is that I want to build a "noise sniffer" preamp. 20-40dB or so, plain old transistors. Here's hoping I'll get by with a single AAA alkaline as the supply because that would allow a pen type enclosure.
