I don’t think either of those is simplifying the setup much. It sounds like it would just be eliminating one of the receivers or transmitters.
The Steam Deck and phone combination was just for an example. I would be setting this up with probably five devices. SteamOS is more or less another Linux distro so I could do something like play in desktop mode and use something like gPodder to play podcasts or input the audio files into Steam or if I wanted to watch a video use VLC’s always in front option for something kind of like picture in picture mode but it’s a lot of individual software solutions for something that could be done a bit more smooth with some kind of hardware mixer.
No I have not. I’ve spent a lot of time browsing the help pages and pretty much every suggestion is the same and when it proves fruitless and the poster and several other people mention the issue still persists they don’t respond.
