I have bought a headphones that has a 2.4g dongle earlier, and it doesn't seem to be outputting any audio at all. The system was able to detect that it is a headphones (see image), but no output. No matter what profile I used it still wouldn't work.
I've tested it on my Steam Deck with Bazzite using its bluetooth mode, and it works. I also tested it on Windows with the dongle and it works. Is there anything I need to do to make it work? Thanks
