PortAudio Error: Internal PortAudio error

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
Error using audioDeviceWriter/setup
