Please bare with me, i'm in full-on rage mode at the moment...
I've been using Vegas Pro since version 4, and even had a mid-level studio at one point (Using Vegas for multi-tracking). I've never run into this before. I am currently on VP10, Win7 NT 64bt, 8core AMD, tons or ram & HD/SD room. Three days ago while recording, all was well. I turned off my Mackie ProFX8v2 (USB Mixer) and left the PC on. Two hours later i turned it on to start recording & nothing worked correctly. Sound was only coming through my PC speakers (Not my powered monitors through the board, as it always does). I checked the settings & it appeared correct, but i was unsure. To be safe i rebooted, same thing happened. I did nothing differently than i have for years. As a last resort i fidgeted with the settings, i tried various configurations with ASIO4all, MS sound mapper, windows classic, and Direct mapper, and finally got something to work. However, now i had track bleed-through that i never had before, a recording volume that was incredibly low, and whenever a track was armed...the meter is already bouncing as if there's a hot mic on it (Producing almost a white noise). Oh, AND...now all of the new recordings are a split second off from the other tracks (Latency, i'm guessing). I unplugged everything & started over (Even though nothing had ever changed), still the same thing. I truly feel that this is a driver issue, but i can't figure it out.
Since then, i have tried (Literally) every configuration of Playback & Recording Device imaginable in settings. Each time i find something that "Kinda" works...but when i save & re-enter any projects, it all goes out the window! Back to square one, nothing working again except for playback through my pc speakers with no working "Input" device. What concerns me, is that i never touched or changed anything...gremlins?
Thanks in advance for ANY help.
