I've already installed the Audio Toolbox in my R2019b, however, everytime time I try to use the function within it, show the error message in below.
I'm calling the function from Audio Toolbox, but the error always shown I don't have "Audio_System_Toolbox".
Please help me fix it, thank you.

License Manager Error -39
User/host not on INCLUDE list for Audio_System_Toolbox.
Contact your License Administrator to review the Options File.

Hello Kevin Lee,
I understand that you are facing license related error while using MATLAB. 
Please note that, “License Manager Error –39" indicates that you are logged into your computer as a user who is not authorized to use the license.
For Network licenses that utilize an Options File to administer the licenses, users who are not included for a licensed product are denied access. Please go through the link below provided by MathWorks Support Team about error -39:

Please update your license manager to the newest version. For more information, follow the steps mentioned in below given article:
