hey everyone,

first, here is my setup:
Laptop: toshiba satellite P200 RT7 (Part number: PSPB6C RT708C)
OS: Windows Vista Home Premium
Recording input: HD Line-in on laptop
Audio output: USB - Serato SCRATCH Live connected to two turntables and a mixer

so, everything was working totally fine until i tried recording this morning...right away i could see that the wave form on the visual spectrum wasn't centered at 0.0, but shifted up to like 0.3-0.4) - see picture...also, the recorded audio was terribly distorted. the only thing that i can think of that may have changed between when it was working fine and now is that i updated the drivers...i tried doing a driver rollback to get the former driver, but it option was "greyed out". uggghhhhh, HELP!

if anyone has any ideas i am ALL ears...i tried reinstalling audacity, did nothing. i tried changing some of the settings in the control panel - sound...still no luck.
HELP!
thanks in advance!!!

Vista still has big problems with sound drivers. We warn people that if they find a combination that works, don't mess with it.

I know how to get rid of the DC level in post (the everything moved up business), that's in Effect > Normalize > Remove DC. However, you have fatal overload and clipping distortion as well. You don't cure that.

One of the posters was able to Step Back his whole machine and return to working.

Did you try readjusting the input level on the Audacity tool bar?

There is also this. Did you go into the Windows Control Panels and try to reduce the level?
