Virtual Audio Output
I would love it if it is at all possible ( I am not sure it is) if you could somehow set a virtual output as the output which could then be used in OBS to allow you to control the volume in there. I currently set my Pretzel to output to a non-used or muted output and monitor it only allowing me to control the music volume independently inside OBS. The reason why I have been doing this is if I just output to the desktop while I have been using the old standalone version I would have to set pretzel to 3-4% which for some songs was not as fine-grained as I would have liked. I just play the music mostly softly in the background too.
