How To Split Audio Sources 1PC
The Google oracle tells me to use Voicemeeter Banana. I also browsed EposVox vid titles but found nothing so specific in my quick scan. Is Voicemeter the only solution? It did occur to me to run my music from an old tablet as an alternative to more software.
I do not know much about Voicemeter and I really do not want to mess with my existing audio set up too much. I also dont want to waste my time learning something new and have it not work for me....
