Calling ofxEasyFft.setup() stops all other audio running in other applications

[DirkBroenink]

When I make a new ofxEasyFft instance and call .setup() then all other audio running on my pc stop working.

Code:
shProcessFFT = new ProcessFFT();
shProcessFFT->setup();

When taking a closer look in the source code I find that it happens specifically on this line:
audio ->openStream( (nOutputChannels>0)?&outputParameters:NULL, (nInputChannels>0)?&inputParameters:NULL, RTAUDIO_FLOAT32,
sampleRate, &bufferFrames, &rtAudioCallback, this, &options);

Line 128, ofRtAudioSoundStream.cpp

I need audio to work in other applications while running my code. Does anyone know why this is happening and/or how to stop it from happening?
