How to load an local audio file into an <audio> src using livereload?

I have this problem where I can not load local audio files into an <audio> src attribute when using livereload because a CORS issue is happening. It works correctly when no livereload is used.

Example:
I use
"http://localhost:8080/_file_/storage/emulated/0/Download/01 A Girl Like You.mp3"

and it throws

Access to audio at 'http://localhost:8080/_file_/storage/emulated/0/Download/01%20%20A%20Girl%20Like%20You.mp3' from origin 'http://localhost:8100' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I have tried set a proxy in ionic.config.json

{
  "path": "/livereload/",
  "proxyUrl": "http://localhost:8080/"
}

and

{
  "path": "/livereload/",
  "proxyUrl": "http://localhost:8100/"
}

it does not work.

Does anybody knows how to do this?
