“Static Noise” from Audio Input When Volume is not Base Level in Pavucontrol

My default audio input is producing “static noises” which I assume is an over amplified sound. I lowered the volume of the input in pavucontrol to the “Base” level and the noise disappeared. I doubt that this is a normal fix though so I looked up similar problems but they were mostly about not having audio output and HDMI-related ones. I tried different solutions from ones I found that are almost exactly my problem and even asked AI for solutions such as setting up rules for wireplumber, alsa, and ‘kernel and/or driver quirks’ but nothing seemed to work.

My Environment:

Device: Acer Nitro AN515-55
Sound Card: Realtek ACL295
OS: Fedora 43 (Workstation)
Kernel: 6.17.12-300.fc43.x86_64

I have tried:

  1. Forced audio input from Monitor of xxx to Built-in xxx (Monitor does not work, for whatever reason)

  2. Removing any kind of boost/gain in alsamixer

  • Setting every Mic Boost to 0 (Sets volume to the base level in pavucontrol)
  • Disabled Auto-Mute
  • Set level of every item to green levels
  1. Set up No-AGC rule
options snd-hda-intel enable_msi=1 power_save=0
  1. Set a wireplumber rule
rule = {
  matches = {
    {
      { "node.name", "matches", *analog-stereo" },
    },
  },
  apply_properties = {
    ["audio.volume"] = 0.7,
    ["audio.adapt.fixed"] = 70,
  }
}

table.insert(alsa_monitor.rules, rule)
  1. Set up Kernel model quirk
#models: dell-headset-multi | alc295-dmic | laptop-dmic | laptop-mic

options snd-hda-intel model=dell-headset-multi
  1. Set up Kernel no DMIC-Detect and AGC quirk
options snd-hda-intel dmic_detect=1 power_save=0
  1. Capped out L R Capture to 22 in alsamix

I’ve been looking up answers and asking AI mindlessly for hours to figure out what’s happening here and at this point, I can only ahope to find an answer by asking directly.
