It would be wonderful if the app could support routing output to multiple sources.
The UI would need tweaking to allow you to tick other output devices other than the primary (maybe by default it only outputs to one source and the default ui stays the same and you have to turn on multiple output in settings… so the ui remains simple for non advanced users)
Other apps achieve the multiple output via a driver that duplicate an input stream and output it to two devices. (Like AudioRouter)
Really hope this can be incorporated…
