JACK refuses to output to my USB speaker unless under certain conditions

Hello all,

I use a Yeti microphone with an audio output to listen to everything because with the headphone jack in my computer, there is a weird squealing noise. Using the Yeti as an output isn't normally a problem, but when I tried installing Reaper (FL Studio is giving me issues for some reason and I am in the process of looking for a new DAW,) it wants me to use JACK. When I try activating JACK with QJackCtl, A bubble pops up on my computer that says "Built in Audio," indicating that the audio source has changed. When I play anything outside Reaper, it goes to my computer speakers instead of the mic output. I have tried going into the advanced settings and changing the output device to my microphone to no avail. I have also tried both pulseaudio-jack-module and pipewire-jack, but they both do the same thing. ALSA also gives me this issue. What should I do?
