[Bug]: Playing Internet Radio via external Player does not work

[verybadsoldier]

What happened?

Problem: When trying to play an internet radio stream using a local player, then the downloaded m3u cannot be played because it is basically empty.

I have set up an internet radio source in the settings like this:

Name: Space Station Soma Stream URL: https://somafm.com/spacestation130.pls Homepage: https://somafm.com/spacestation/

Then it shows up on the left side pane. When I click the play button using the web player, it starts playing without issues.

When I use it with a player setup as External player with playlist then a m3u is downloaded when clicking again play on the internet radio. But I cannot play it in my media player.

The content of the m3u is just empty without any further content:

#EXTM3U

Thanks for help!

Steps to reproduce

1. Setup a player External player with playlist
2. Add a internet radio entry using e.g. https://somafm.com/spacestation130.pls
3. Select the player added in 1. and select play on the left side pane
4. A m3u will be downloaded but it is empty and cannot be played
