I use an audio interface with bookshelf speakers... mostly overkill for people who don't make music because they have xlr and line level inputs for using a professional mic.
Do you have room in your computer setup for two bookshelf speakers at ear height? Because otherwise, I'd recommend a sound bar type of deal.
Cycling kickstarters have an awful track record. Make sure it's make by an actual cycling company and even then it's better to do a late pledge after some fulfillment and reviews.
Don't use regular Arch if you're struggling. There are some arch-based distros that are more user friendly, though. Like EndeavourOS or ArchMan. Manjaro can be good too but there are legitimate problems with how the project is run.

Also, you may want to set the Desktop Environment to Xorg or X11 (same thing) if Wayland is causing you problems. It's older, but in some cases more efficient and less experimental. Check out the section: Switching desktop environments using a graphical user interface. It should look similar to the pictures. And notice that the "gear" icon may not appear until you select a user or start typing your password.
If your problem is different than this, open a support ticket in the discord or forums of the distro you're using. Linux Mint has a great system for this on Discord.
Klipsch has been a consistently good brand for a long time. I checked on ebay and there's some great ones for $200 to $300. Only 2.0 setups for that price, though.
You will need an amp for those unless it's got a built-in amp (some models have that).
