Electrical Specs for Motherboard Audio

[alvis1]

Does anyone have or know how to get the electrical specs for the audio ports for a Compaq PC that uses the MS-6577 M-ATX Rev 3.1 motherboard. I can't seem to get them from the "technical help" folks that support the PC's. I would like the impedance, voltage, and current info for the "audio in" "audio out" and "mike" ports.
Thanks, Al.

I don't know myself, but I think it's something like 10-25W

Don't mess with Compaq support. That MS is a MSI board.
