I have connected my Ubuntu 20.4 desktop computer with my av-receiver to get audio output via HDMI to my sound system. This is working, but it has the side effect, that my av-receiver is also recognized as a display device. Thus, in Settings → Displays I now have a third monitor. This is not ideal, because my mouse sometimes disappears into that area.
When I disable the display, then not only the video but also the audio is gone. So how do I treat my Yamaha av-receiver as an audio device only?
