PortAudio Error: Internal PortAudio error

I am getting PortAudio Error: Internal PortAudio error, running an audio example >> audioTestBench('audiopluginexample.Echo')

Run Audio Test Bench on Mac.

Attempted changing output device, same error.

Data point: that example works for me on my MacOS Catalina system.

Tried simple audioread:

[data1, fs1] = audioread('OH.mp3'); 
sound(data1,fs1) 
%plot(data1) 

>> Phase Error using sound (line 79)

Device Error: Internal Device error

Error in Phase (line 8)

sound(data1,fs1)

What about if you

sound(rand(1,1000))

... On the off chance that fs1 from the file is not compatible.

Thanks for the suggestion I appreciate it. I am using an external interface FF800 > thuderbolt. I then changed the internal sound to the Mac speakers in the hope this was the problem. Off/On reboots many times, then updated Matlab. The probelm started when I opened the audio test bench and tried to play a file, since then no audio will play. The sample rate of fs1 is 44100

Same error,

Error using sound (line 79)
Device Error: Internal Device error

When I check line 79,

 play(playerObj(end));
catch exception
    throw(exception);
    end

So I took the nucleur option and uninstalled version 2020 and installed version R2021a. Using the just the mac audio. Attempted to load the handel.mat file same error:

>> sound(y,Fs);
Error using sound (line 79)
Device Error: Internal Device error

So just tried this:

>> deviceWriter = audioDeviceWriter;
>> info(deviceWriter)

ans = 

  struct with fields:

                   Driver: 'CoreAudio'
               DeviceName: 'MacBook Pro Speakers'
    MaximumOutputChannels: 2

>> sineGenerator = audioOscillator;
>> count = 0;
while count < 500
    sine = sineGenerator();
    deviceWriter(sine);
    count = count + 1;
end
