Avid Core Audio Manager don't change the Sample Rate
 

Hi everyone,
I am new user on this forum.
I have two problems with CAM:
The Sample Rate is setting at 44,1 kHz, and I can't change it.
I want to use my HDX Card with other program like Waveburner, Logic10 and so on…but they don't see Avid Hardware.
I try to delete the preferences (com.avidCoreAudioManager.plist, com.ProTools.plist and so on..) but I haven't no lucky…
Can someone help me?
I have PT HD 11.1.2 on Mavericks 10.9. Mac Pro Quad Core 2,66 16 Gb Ram. Hardware Avid HDX.
Peace
