Pro Tools with UR824


I just switched from Cuebase to Pro Tools, If I have a mic connected to input 1 on the 824, it doesnt matter what assignments I have on the track in pro tools, even with the input not assigned, I get the audio from the mic routed through all outputs from the 824, The DSP GUI is over riding Pro Tools, I have the 824 set as the audio engine in pro tools, also I noticed I can only change the buffer size from the DSP GUI, not from pro tools. I can play back a session in pro tools just fine. I cannot figure this out. The only way to mute the mic is through the DSP GUI.
