Audio features from base MATLAB, such as “audioplayer”, use the “DirectSound” audio host which is limited to 192kHz. This causes the mentioned “Unanticipated Host” error.
A workaround for this is to set the driver to “WASAPI” or “ASIO” using “audioDeviceWriter”, as these drivers do not limit the sample rate to 192kHz. This requires a license for the Audio Toolbox.
Sample code to set the driver to “WASAPI” is given below:
%Set driver as WASAPI or ASIO
adw=audioDeviceWriter("Driver","WASAPI","SampleRate",384e3);
%Using pinknoise as sample audio
adw(pinknoise(1024*16,2));
To get the name of your output device to pass as argument, the “getAudioDevices” function can be used to list available devices for the selected driver:
getAudioDevices(adw);
More details on “audioDeviceWriter” and “getAudioDevices” can be found in the documentation below:
Hope this is helpful!
