What "card" are you talking about?
As MissD asked before:
- what streaming host do you use? I use MyRadioStream
- what player do you use? I use WinAmp
- what music format do you use? Gizmo made a post a couple hours ago on Discord that only MP3 and OGG is working, ACC does NOT! I use MP3.
- is your music streaming link working when you put it in any browser?
- you DO have a radio object in your room and you put your radio stream link in there and clicked on play?
- remember that there is NO sound in the changing room in 3DXC
- you followed all the instructions in this "manual": Streaming music into 3DXC chat rooms
