Re: C-Media CMI8738-LX noise in recording from line in

OK. but the question is, does it put noise in recording in windows as
well? I maybe solved it w/ activating the old hd audio integraded snd
card, whichs broken, but line-in works and i tried it recording w/ it
and that works perfectly. you say, that the cards never going to have a
good sound quality. I am sure it doesnt, but what I am getting isnt
even good enough. there is written on the box that I can record with it
in 44khz and so on, cd quality and whatever, so is it a lie?

i tried out manipulating w/ the mixer, believe me, however, i ll post
some output later, but the settings can not be set better, because the
only relevant setting here is the line-in and that is already on
maximum. the second thing that i dont understand about this card is,
that when I play sth at line-in, the sound is perfect, but the
recording is crappy. so does it have a line-in to line-out passthrough?
but then hows that possible that I can regulate it on my mixer and even
mute line-in completely?
