So I am finally putting in the effort to move over my music production suite to my linux PC, and genuinely this is just better than windows audio. The only thing I have not been able to replicate is how ASIO would bypass system volume.
This was useful because it allowed me to keep my audio workflow and everything else balanced seperately.
It was also really useful in foobar2000 (now replaced with the much nicer fooyin) because of replay gain. Replay gain would keep each song in the same loudness range allowing me to set my desired volume with my audio interfaces physical knob.
Now if I want to replicate this workflow I need to max out the system volume which removes the ability to quickly equalize the two workflows.
I hope I described this in an understandable way.
I use Fedora KDE 44 with the audio group installed (so jack and pipewire)


Try Helvum (https://github.com/relulz/helvum).
there are probably simpler apps that can work for OP. I recall seeing one called Pavucontrol or something on Flathub.
