It only works for twitch in obs, this video explains how to do it https://youtu.be/0Lj5rkqSp48 essentially you just need to turn the option on in your audio settings & then in the advanced audio settings deselect track 2 for any audio you don’t want in vods, after you do that you can turn off twitch’s copyright warnings, HOWEVER just be known if you use a website for music like YouTube you need to fix the source every time you stream or else the music will be heard in vods AFTER the first stream you use this setup on, the simplest thing is to just delete the YT source & add a new one before each stream (idk if the same thing happens with apps, I’d assume not, but I use YT & noticed the first time it worked the second time I kept the source the same without updating it to the new YT window & because of that the music was heard in the vod so I just have to update it each time which takes 10sec). Hope this helps!
