Reply to Traktor Audio 2 absurdity!

Hey guys! New user, crossposting this from the NI user community s to hopefully get more of a response! I've searched around a lot there and here, and not found a fix to my problem yet.


My shiny new Audio 2 interface arrived a few days ago, finally saving me from the plights of stereo splitting once and for all (I thought

There are some severe problems which I just can't work around though, even after 2 solid days of troubleshooting. Maybe someone in here can help me out with these issues -

- Pushing the master channel to full volume on the interface causes severe popping
- Even at around 70% volume, latency spikes dramatically leading to stutter/temporary dropout


A few details:
This is reproducible across 4 separate machines. Specs of the machines I tested on range from a 1.5GHz 2GB touch input notebook to a 2.9GHz Dualcore 6GB desktop. Symptoms remain pretty much the same.
Edit: I tested on both Traktor 2 and Traktor 1.2.4
Each system was optimized before testing - WLAN disabled, windows classic theme, all but vital system processes purged etc
Latency was monitored using not only the TA2 control panel, but also DPC Latency Checker and examined further using LatencyMON
Every single latency and buffer combination in the control panel was tried over and over
All troubleshooting steps rinsed & repeated


Its been a frustrating few days - I thought this buy would make my setup a lot simpler and smoother, but no matter what I play around with, the PC's onboard integrated audio runs better than my new TA2.


..Help!?


PS: does anyone know where I can find the older 2.x driver for windows instead of the current 3.x? I've heard from a few sources that its a lot more stable.
