How to access kinect audio device using libfreenect correctly

I use an Kinect, Model 1517, and cloned the master branch from the OpenKinect/libfreenect repo to my Ubuntu 14.04 LTS x64. My target is to do some fancy stuff with the build in mic-array.

But if I want to test the sources and execute a sample program, I get following output :

$ ./freenect-glview 
Kinect camera test
Number of devices found: 1
Could not open audio: -1
Failed to open motor subddevice or it is not disabled.Failed to open audio subdevice or it is not disabled.Could not open device

During compilation no error or warning is pointed out. With debugging I isolated the failure to the initialization of FREENECT_DEVICE_MOTOR.

I also tried to download the stable package version, using

$ sudo apt-get install freenect

but (not in freenect-glview but in other samples) this error occurs too.

What differs from all the tutorials and guides I read, is that after the command $lsusb the output just shows three devices named 'Microsoft Corp.', instead of a longer description like Bus 001 Device 006: ID 045e:02ad Microsoft Corp. Xbox NUI Audio.

Do you have any plans, how I can fix this Problem? I assume, if it doesn't work in these samples, that it also wont work in an selfmade one.

Try running with administrator privileges. I had the same problem and that worked for me.

$ sudo ./freenect-glview
