This might be a problem of not having enough power to supply the attached device. I noticed that when I use the docking bar with hdmi, a wireless mouse and a wired keyboard connected to it, the screen turns off, it doesn't work. If I either remove the keyboard or the mouse or if I power the docking bar via the USB-C port, everything works. So maybe your sound card draws too much power for the phone itself. Unless you didn't have power going into the docking bar, then it must be something else.
