Unfortunately, I have come online to echo the sentiment. My Audiobox USB 96 is popping when I play audio - When I use my TAC -2 (Zoom) it odes not happen. I have uploaded the most recent drivers and checked to see that everything is on the same sample rate but still I hear pops.
If it is that the Presonus USB 96 is causing this, I doubt it can be anything else, then it is totally unacceptable for an audio interface to be sold that produces such noise. and I am troubled that PreSonus have not yet responded to our valid concerns.
I hope it gets sorted quickly as I can't record any vocals like this.
