doesn't find audio harware

when i want to play audio through matlab by use of audioread i get this error saying it doesn't find any audio hardware

> In audiovideo.internal.audioplayerDesktop.hasNoAudioHardware (line 566)

Playing audio would require a function such as audiowrite() or sound() . audioread() is for inputting sound into MATLAB.

Quesiton: are you using MATLAB Online? If so then there is only audio capabilities if you are using the Chrome browser.

Hi Kevin,

The issue might occur because of multiple reasons, to troubleshoot, please ensure the following:

Verify the Audio File:

• Ensure that the audio file is not corrupted.
• Try playing the audio file using any media player to confirm it is working correctly.

Check MATLAB Preferences:

• Open MATLAB and navigate to Home > Preferences > MATLAB > Audio.
• Ensure that the correct audio device is selected. If no device is listed, MATLAB may not be detecting your audio hardware.

Use Appropriate Functions:

• Use the “audioread” function to read the audio file.
• Use the “sound” function to play the audio file.

Refer to the code below to help identify the root cause of the error:

% Read the audio file
filename = 'sample-3s.wav'; % Replace with your audio file
[y, Fs] = audioread(filename);

% Check if audio data is successfully read
if isempty(y)
    error('Audio data could not be read. Check the file path and format.');
end

% Play the audio using the sound function
try
    sound(y, Fs);
    disp('Playing audio...');
catch ME
    disp('An error occurred while trying to play audio.');
    disp(ME.message);
end

For more information about the "audioread" and "sound", refer to the below MATLAB documenation,

sound: https://www.mathworks.com/help/matlab/ref/sound.html

If the issue persists, could you please share the audio file that is causing this error? So that I can investigate the issue.
