URL aceppted by Simulink "FromMultiMediaFile" and not accepted by "AudioFileReader" system object

The Simulink dsp Toolbox block "From MultimediFile" aceppts the following Url as "filename" input: mms://apasf.apa.at/oe1_live_worldwide.

The dsp.AudioFileReader sytstem object does not aceppt the same Url. The follwoing lines of code produces an error: "Error using AudioFileReader/setup Input File specified not found" Error in matlab.system.mixin.FiniteSource/isDone (line 38)

hmfr = dsp.AudioFileReader('mms://apasf.apa.at/oe1_live_worldwide');

hap = dsp.AudioPlayer('SampleRate', hmfr.SampleRate);

        while ~isDone(hmfr)
           audio = step(hmfr)
           step(hap, audio);
        end

What kind of URl do i have to use with the "AudioFIleReader" object in order to make this work?
