Even better -
use the Faders for each channel in Vegas Video to reduce the output volume.
The latest version has a bug where the output of the audio is louder than it
needs to be by about 6db or so. You may have to Drag the fader window wider to see the Pan L/R and the output fader. Basically, this is your level set going to your output buses, and is independant of the volume automation of the track, meaning set this so it does not distort, and use the volume automation to bring up or down the volume of
certain components (such as ducking the music bed manually while doing a voice over
in a documentary)

How did you determine this?

I found this out by recording into Vegas using the direct outs on the Mixer going into a Delta 1010 set to +10 db input calibation switch on input, and also +10 db on output, (using the 24 bit recording). Strangely the output came out being distorted, even though I did not normalize, increase the volume, or anything like that. It played back louder than it should have. Using the tape returns on the Mackie 2408 for playback...
It should not have disorted on playback as it should have been 1:1 ratio (Unity Gain) going in and out. The input meter did not clip or show any signs of overloading.
So as long as what's going in == to what's going out there should have been no clipping. Therefore I concluded it was the output of the s/w which was slightly over calibrated, and when decreaseing it betwwen 3-6db the problem went away. It did not happen in Vegas 2.0 with the same system, and this also happened on a Motu 2408.
Not that I am complaining, I can use an extra 6db of output, but it overloaded the mixer inputs (some analog, some lightpipe....) I dunno, maybe this is a result of the 24 bit recording method, and dithering in the software package...who knows, I just know how I solved the problem.....Could be the Delta and Motu 2408's ASIO driver versus the DirectX driver.....microsoft deals with 24 bit wave files differently I have heard...

+10 ? You don't mean -10 do you ? Why are you blaming Vegas for something that (if not a methodolgy cockup) is the fault of your mixer(s), soundcard, or drivers ?
