Amarra = no sound after Pure Music installed

Hello Everyone,

I am fairly new to the PC music world but for better or worse, I've jumped in head first. I have the Weiss DAC202 running with a MACmini and I have been using Amarra successfully. I am currently listening with a pair of beyerdynamic T1s while I wait for my Revel Salon 2s to arrive (will be mated to a pair of Pass Labs XA100.5 monos). As a side note, I changed out the standard Radio Shack firewire cable with an Oyaide firewire cable - Very Nice change... smoother, more detailed, etc.

Now to the problem: I added Pure Music's Channel D software and Amarra no longer puts any sound out to the headphones! Coincidence or software sabotage!?

Any suggestions will be welcomed.
