Here’s a well-written report you can copy-paste to the Garuda Linux forums to get help from the community:

:microphone: Mic Static Noise Issue on Garuda Linux (OBS & Audacity)

System Info:

OS: Garuda Linux x86_64
Host: Lenovo ideapad 81DK
Kernel: 6.14.2-zen1-1-zen
DE: KDE Plasma 6.3.4 (Wayland)
WM: KWin
Mic: Built-in laptop microphone
Audio System: PipeWire (confirmed via systemctl)

:hammer_and_wrench: Issue Description:

Whenever I try to record my voice using OBS or Audacity, I get a very loud static/buzzing noise, like the sound of a disconnected cable box. This happens even when I’m silent.

  • I’ve tested in OBS, Audacity, and using arecord — the issue is consistent.
  • The problem is with the built-in laptop mic.
  • The system sound and playback work perfectly fine — only the mic recording is affected.

:white_check_mark: What I’ve Tried So Far:

  • Reduced mic input level in pavucontrol
  • Disabled echo cancellation and other effects
  • Checked alsamixer:
    • Mic Boost set to 0
    • Capture volume lowered to 70%
  • Restarted PipeWire services:
    systemctl --user restart pipewire pipewire-pulse wireplumber
  • Confirmed correct input device is selected in OBS and Audacity
  • Tried different noise suppression filters in OBS (RNNoise, Speex)
  • Disabled all unnecessary audio input sources

:test_tube: Additional Notes:

  • The noise appears regardless of app (OBS, Audacity, even arecord)
  • Using Wayland session
  • Not using any external mic or USB soundcard
  • Uptime at the time of test: 34 minutes

:folded_hands: What I Need Help With:

  • Is this a driver or PipeWire config issue?
  • Any way to properly calibrate or clean built-in mic input on Garuda?
  • Would switching to PulseAudio help in this case?
  • Should I consider a USB mic or external audio card?

Any help would be appreciated — I’d love to get clean audio working for game commentary and videos!

Thanks :raising_hands:

Sorry, but generated garbage from a pseudo AI ends up in the trash here.

Next time you open a topic, describe your issue in detail and above all without a pseudo AI - you should also follow the topic template and post your garuda-inxi.

For something like this you should generally use an external microphone.
