Need help finding a replacement for some shitty name-brand audio software

Sorry guys I don't know where the right place to put this question is. I hope it fits here, just lmk. I have a problem with my current audio software (Steelseries Sonar) wherein the issue is it is fucking dogshit and keeps crashing and generally just sucks gorilla balls. However, I kind of need it. It's the only one I've found so far (tried Voicemeeter too) that lets you somewhat efficiently manage multiple audio channels to the same device -- a godsend for me because I like to have different apps run through different channels I can adjust on a whim, and OBS lets me filter out some of these entirely so I can play games with youtube in the background and not worry about that getting picked up in a clip. Or I can mute the discord voice call in post-processing, if my mates are going crazy (a common occurrence). Does anyone know any other software that meets this mark? I'm typically using ~3 different devices a day (Bluetooth headphones, speakers, and wired headphones for gaming), and I'd like a quick way to interchange these while keeping app channels consistent.
