The microphone is detected, but input is just noise.
Any idea what might be wrong?

Re: Headset mic (3.5mm TRRS) only produces static noise on Arch Linux

Stereo input is often a lie and not handled properly. Try muting the left (or - if that didn't help - the right) channel, does that fix things? Do you know the mic to be working on other systems? Can you post 

amixer -c1
pactl list sources
pactl list source-outputs

during the issue? Also please wrap outputs in   [code][/code] tags and edit your post in this regard

I tried switching ‘Headphone Out’ to ‘Mic In’, but it actually made the static noise much worse. I also tested muting one of the stereo channels, but that didn’t make any difference.

Re: Headset mic (3.5mm TRRS) only produces static noise on Arch Linux

Simple mixer control 'Headphone Mic Boost',0
  Capabilities: volume
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 3
  Front Left: 3 [100%] [30.00dB]
  Front Right: 3 [100%] [30.00dB]

Does it help to turn  off the boost?

amixer -c1 sset "Headphone Mic Boost" 0

Re: Headset mic (3.5mm TRRS) only produces static noise on Arch Linux

I already tried turning off the "Headphone Mic Boost" using amixer -c1 sset "Headphone Mic Boost" 0, but there was no noticeable difference. The static noise is still present.

I also tried switching from the headphone/mic combo jack to the mic input, but that actually made the static noise worse.

I've already tried several other basic troubleshooting steps (adjusting levels, different settings, etc.), but none of them resolved the issue.

At this point, I'm starting to suspect that the motherboard's onboard sound card might not be fully compatible or properly supported, and I'm wondering if using an external sound card would help.

suspect that the motherboard's onboard sound card

amixer -c0

Though the noise goes away when removing the Headset? Or can you only hear it via the headphone? Do you get it using some throw-away in-ears?

Static noise is typically a feedback loop (also output plugged into input) or coil whine picked up by the audio.
Is it load dependent? Do you get it when only booting the multi-user.target (2nd link below)?
