Chomecast support

Good morning,
Just wanted to report that Chromecast support doesn’t seem to be fully supported by FydeOS. As far as I’m concerned, my Harman Kardon Omni+ speakers don’t appear in the taskbar (attachments) while my Android boxes do. It’s surprising because when I go through the cast function of the internet browser, my speakers are displayed. I am therefore curious to know if the problem comes from the fact that it is a question of casting only audio or then because of the speakers whose version of the chromecast must be old.

I’m using a Jumper EZbook 3 Pro (N3450, 6GB) running FydeOS v16.1
