My audio on Linux sucks ass. Anyone had encountered it before?

So, I have USB fifine mono mic, it was mono that was coming only into left ear, couldn't find a reliable fix for a while but I fixed it barely with the help of Claude AI.

Now, I have issue of whenever I'm booting into my Linux, there's 40/60% that I might need to restart my pipewire trough terminal, because I can hear myself when I'm talking (it translates to also bleeding out ANY of my PC sound trough the mic, which means folks can hear themselves, and my audio of PC any app).

Another issue, is that I'm a speakers user (belive me, it's great thing when you do be living alone), and so my microphone currently configured a way that its chomping my words whenever there's EVEN A LITTLE BIT of PC noise exists (like a music on a really low volume). On top of that, when I open up "EasyEffects", I pray for my virtual connections not to mess the fuck up, because by the use of "helvum" I can see how simple my audio connects to all necessary devices, and when I open "EasyEffects", it's make big glorb.

Idk how the fuck my setup works in all honesty, it's a mess of attempting and failing, so it's also a discord fault to some degree.

In a moment of slight rage I've hitted my mic quite hard, and I've splattered it open but it's still working, thinking to buy SM58 and U-phoria UMC22, any other audio suggestions for Linux?
