I'm running Windows, and I'd like to feed both the s/pdif input of my interface with one of the xlr in's to Skype, but I can't find anything that will do this. Unless I'm missing something, I've tried Jack, Virtual Audio Cable, Voicemeeter Banana, etc. and I can't get any of them to do this. I know Soundflower on OSX can do this. Thanks in advance.
