realtek

Hi I have a little problem ( also this could help some peoples with the same problem ) I tried to record some stuff in game and on my desktop with OBS and noticed my sound had a echo... So I spent hours searching where it could come from, trying all solution I could find on the web, nothing...

I installed Voicemeeter Banana some time ago, and at one point, wanted to use it as my main device for Desktop Audio. Since then, OBS won't register any sound on my Desktop Audio if Realtek Audio (which had been my original default) is selected, even though it's playing fine through my speakers...
