Of course! I had a feeling I explained it poorly ha
the Xbox one and Xbox one x(if you want UHD features) have an HDMI in port that can be accessed right from their built in tv tuner app. Despite the name it doesn’t need to be a cable box any HDMI device will display through it
So I have an hdmi splitter going into it, with my switch and PS3. This allows me to just open the tv tuner app on my Xbox (either with controller or even my smart home devices like Google home) to view whatever my HDMI switch is set too. While still having full access to my Xbox at the same time. I can pause my ps3 or switch game. Go to Spotify or even YouTube, and swap back to my game no problem.
Bonus points background audio still works too so I can even play Spotify while still getting audio from the HDMI in. While also still being able to “mix” the Spotify audio from the Xbox guide menu so you can adjust the audio however you want. Want more game audio and just slight background music ? Just adjust the slider!
Hopefully that makes a bit more sense I feel like it’s a bit of a ramble ha. But if it is feel free to ask me to elaborate further I don’t mind
