[solved] Audio output through soundbar connected to screen

Hey everyone!

I’m running Archlinux on a desktop PC (Asrock B450m pro 4, AMD Radeon Pro WX 2100). The packages mesa and xf86-video-amdgpu are installed. I’m using two screens, both Dell P2418D. One of them has attached to it a Dell Professional Soundbar AE515. Previously, I had this soundbar directly connected to the PC via USB, but due to a change in the setup (another machine using the same screens), I had to change this.

Now, the soundbar has its USB cable plugged into the screen. pavucontrol only lists a Dummy output. But

How do I configure alsa to use the soundbar as audio output device?

Edit: The soundbar was broken. Everything worked well after I replaced it (same model).
