[podcasters] Vista distorting Audio?
JM Campbell
So, I got a new PC and figured that would be the perfect opportunity
to finally switch my mixers (upgraded to a Mackie DFX-12) and the new
PC is a Vista (Yes, I know "vista, ick." "why didn't you buy a mac?")
Anyways, when I try to play audio off of the Vista PC I have a 1/4 to
1/2 cable from the PC's line-out to the line-in on the mixer. I have
my headphones plugged into the mixer. The audio coming from the PC
sounds distorted with digital noise and clipping. If I plug headphones
into the PC it sounds fine. It's this way with MP3s and WAVs.
I'm wondering if this may be some kind of anti-piracy protection in
Vista that knows it is plugging into a mixer or recording device? I
did a google search and have not been able to find anything. I guess
the next step is to try and plug into the old mixer, see if it's a
mixer issue.
If not, any clues on how to bypass this?
Anyone know what else might be causing the issue?
Also if I take the PC line-out into a mic preamp before the mixer will
that help boost levels at all?
Thanks for the help

Sounds to me like you already have too much level. WHERE on the mixer are
you plugging in? I know you said "line-in" but where exactly? Is there a
fader that controls that jack? If not, try plugging it into a jack that is
controlled by a fader and see what happens.

Here's a big picture of the mixer.
I'm plugging in to the line-in on pot 3.
When I adjust the gain and fader I either hear very low audio (not
high enough to record) or the cracking and popping audio.

No, sound cards aren't that smart yet. Vista does play those sorts of
games with monitors and video, but an audio jack is an audio jack.
(Unless it's digital audio. But never mind that.)
The only thing I can think of to suggest -- and you were pretty
specific about what you were doing, so this may be redundant -- would
be to make sure you really _did_ plug into the line out jack of the
card and not the headphone jack. Many sound cards either combine the
two and let you switch them in software, or they're unclearly marked.
I've probably lost hours of my life staring at sound card jacks to try
to make out the little etched symbols, and then trying to figure out
if each one refers to the hole above it or below it.
Headphone levels are *a lot* louder than line level, and if you're
sending a phone-level signal to the mixer where it's expecting a line
signal, it'd be very common to get the sorts of distortion that you're
talking about.

I think you got it right, Steve. documentation describes it as a
line-out, but I guess it is a headphone pot.
But after futzing around with it a couple hours. The simple solution
was just to plug into pot 5 and 6 instead of 3 or 4

I plugged into the L port of pot 5 and everything sounds fine.
So far a really good mixer, I haven't played with the effects yet, but
I like it so far. And it's awesome to play audio and have the person
on skype hear it.
