how to upload audio files via Media

[jasperjiasc]

I saw https://sonicjs.com/roadmap saying 3 types of audio files can be uploaded via Media page. But it does not allow in the app. And after I create a folder, it is not shown in the dropdown list of upload in folder in the pop window.

I found storage tab in the setting page allows to enter different file extensions, but it can not be saved.
