I need to connect aux as an output for the ANC model while integrating RPi with matlab. The port for aux cable is not available when i run
a = listAudioDevices(r,'capture') on matlab.

If it is an audio output(plyaback) device, you would have to use the below function to get the list of playback devices
a = listAudioDevices(r,'playback')

Hi @Sachin,
I can see that there is an error in the MATLAB support package directory. I suggest you reinstall the MATLAB Support Package for Raspberry Pi Hardware. You can download this add on from here:
https://www.mathworks.com/hardware-support/raspberry-pi-matlab.html
Also make sure that your Raspberry Pi Model falls under the supported hardware for this package.
After that you can initialise the connection between the audio output and Raspberry Pi using the ‘audioplayer’ object and use the ‘play’ function to play audio. You can leverage the following documentation to setup your audio output for your raspberry pi:

Hope these troubleshooting steps solve your query
Thanks.
