Doesn't look like that menu indicates your avr as a playback device, is it currently connected? Looks more like on-board audio choices for your pc. When I connect my pc to my avr I have my Denon avr specifically available as an option in sound output settings.\n\n\n\nIf the PC monitor, TV and projector are all connected to the graphics card, you should be ok. Realtek is onboard audio and would output to the PC speaker connections on the back of the PC. Some devices use USB for audio, and I assume you have an Oculus device that is showing up as Rift Audio. NVidia RTX Voice should be the graphics card. The AVR should not care whether you are using the TV or the projector. When set to NVidia, the AVR should receive audio over HDMI and you can either view the image over HDMI from the AVR to the projector, or directly from the graphics card to the TV. If the TV is using VGA, DVI or a display port connection, that is video only and you'll need the AVR for audio, or switch to the PC speakers.\n\nThe PC doesn't do any audio processing over HDMI, it should just pass the signal to the AVR. The PC would do audio processing if, say, you had a 4.1 PC speaker setup connected to the speaker jacks or to USB.\n\n\nHi guys, so the pieces finally arrived! I have a ton to share but first I'd like if you guys can help me with the source configuration, as I suspected I'm having issues using the speakers with the PC and TV.\n\nIt works great with the projector, but I'm unable to switch from the projector to the TV screen without losing the tower speakers signal.\n\nRemember this TV is connected to the graphics card. All I do is switch from my gaming monitor to the TV signal as if it was a second monitor. In short: I'm unable to use the speakers with the PC the Sony AVR doesn't show up in the list of playback devices.\n\nIt only shows up when I switch to the projector\n\n\n\nThis is how it's connected:\n\n\n\n\n\n\nWhen I'm using the PC monitor or TV as monitor, it uses my PC speakers which are connected via 3.5mm jack., I'd like to be able to switch from those to the tower speakers, without having to turn on the projector.\n\nCan somebody help me? ;( I don't always use the projector screen, I use the TV too for some series.
