Hey Mecky,

Have tested it with following flow, which downloads an mp3 from the web and plays it in the browser:

I run Node-RED on a Raspberry PI 3 model B and did the tests in browsers on Windows 10. It works fine in Chrome/Firefox/Edge both for flow editor and dashboard. So **6 tests** in total ...

A couple of remarks:

- The output of my http-request node is binary buffer. Don't convert audio or video anywhere to strings ...
- In the audio-out node I have selected the checkbox '_Play audio when window not in focus_, because it won't play otherwise when the tab (where you have added your audio-out node) isn't visible at the moment ...
