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.

Try picking the “Disabled” option for each dropdown.

I believe that you can choose it in the list of options that appear when you press Proaudio, for example

I had this problem too and solved it by just telling the OS not to use those “devices” through that same same GUI in the picture.

You can click the dropdown labeled ‘pro audio’ & set it to another option, that should vastly simplify the bars. I don’t know much if you’re using pro audio intentionally.
