Is it possible in Bazzite-Gnome to connect a 7.1 channel AVR via HDMI, but without adding a second display at the same time? My monitor is connected via DisplayPort, and I’ve got nothing connected to the HDMI out of my AVR. Nevertheless, Bazzite always adds an “invisible” screen, causing my mouse pointer, windows, login prompts and the occasional game go lost on the screen.
I only want HDMI audio, not video on the same link.
