From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I would like to get rid of some of these random audio outputs and options but I'm not sure what to do.
I am using Arch with KDE and have no idea why there are so many options for audio.
It can be a pain to get the mic and headset working like it should (with the mic) and having all of these inputs/outputs is quite frustrating.
Any help would be greatly appreciated.
You have so many options because your system has a lot of audio output options available. Presumably your mother board or your graphics card display outputs given the "Navi" label.
As others have said, from that section of the settings you should be able to click on the "proaudio" drop downs on the right and disable any you don't want to see.
The Navi outputs are the audio available via your hdmi and display ports - you may want to keep those on if you ever want audio from the screens directly but if you don't ever use audio from your displays you can disable the audio outputs. Most people don't use screens with integrated audio output but some may plug headsets into their screens via 3.5mm cables so may want it. But that's an usual use case - most would plug into the PC itself.
The starship/matisse HD audio is your audio jack on the front of the PC (often USB provided) - I'd keep that one available if you ever plug in your headphones. Personally I have my noise cancelling headphones plugged in via audio jack - you get perfect uninterrupted audio and longer between recharges as the headset doesn't have to use Bluetooth. However may not be desirable if you're using a mic on your gaming headset too.
You then have your Bluetooth device itself which is the gaming headset.
The other devices below that are your microphones. Again you will have multiple inputs which you can disable if you don't use them.
Just remember in the future if you ever want to plug in something that you've disabled these devices here.
Thank you for the explanation.
I did notice that they said HDMI/DP but didn't really put two and two together to understand that it was for each port. Makes more sense now.
Also didn't know what the starship/Matisse was either.
