Re: Audio question - mic-in/line-in

I know that, on Windows, almost all machines I use (laptops and
desktops) now let me adjust the gain of the mic-in. Apparently, this
gain ajdustment lets you select anywhere between line-level and
mic-level. I figure that this adjustment isn't just software (ie,
Windows), but some adjustment that's being made to the card itself. So,
it's a matter of whether the kernel supports it and whether the current
set of sound mixer tools do as well.
There seem to be very few notebooks which have a line-in jack, but
more which list a combination mic-in/line-in. For instance, the acer
aspire 1520 and the asus Z9000 both seem to sport this feature. Do
these ports automatically detect the line level and self adjust? Is
it purely a hardware feature or is special support in linux required?
What'd I'd do (in fact, it's what I'm *going* to do when I go shopping
for a new laptop next week) is bring along a recent Knoppix (or other
full-featured live-cd) disc and boot it in the various laptops and see
if you can adjust the recording gain anyhow.
