I tried to boot Fedora Workstation 41 and CachyOS on a Live USB, and lo and behold, no crackling noises. Tried Manjaro on Live USB, and still noises. So it’s probably a software issue, something to do with Manjaro’s settings for PipeWire.
I ended up installing CachyOS as I wanted an Arch-based distro, and so far so good.
Ok, so far so not good. I booted up today and the crackling was back.
It still works fine on the CachyOS & Fedora Live Images, and I suspected it might had something to do with the kernel, as the one on the CachyOS image is 6.12.6-1-cachyos and the latest one at the time of writting is 6.12.9-3-cachyos, but I downgraded the kernel back to 6.12.3-1 and the problem was still there. The version of the sound server (PipeWire) is still the same, 1.2.7.
So, I changed the sound server from new and shiny PipeWire to “good” old PulseAudio, and… It works!
You just have to install PulseAudio. E.g. for Arch-based distros:
And then test it works (you might need to restart the application you use to test it, e.g. Google Chrome – I use a simple online tone generator) by stopping PipeWire with:
systemctl --user stop pipewire.socket
If it fixes it, you can disable PipeWire from launching on startup with:
sudo systemctl --global disable pipewire.service
TIP: you can see your current audio server with inxi -A:
$ inxi -A
Audio:
Device-1: Intel Meteor Lake-P HD Audio driver: snd_hda_intel
API: ALSA v: k6.12.9-3-cachyos status: kernel-api
Server-1: PulseAudio v: 17.0-43-g3e2bb status: active
I updated the firmware through LVFS (fingerprint sensor v. 01000334, Intel Management Engine v. 2141, UEFI dbx v. 20241101, BIOS v. 0.0.3.4 for the Intel® Core™ Ultra Series 1), installed the brand new 6.13.0 kernel, and it now works with PipeWire!
I don’t know what exactly fixed it, but I’m very happy.
For newer versions, add a /usr/share/wireplumber/wireplumber.conf.d/51-fix-crackle.conf file (or /etc/wireplumber/wireplumber.conf.d/51-fix-crackle.conf to keep it out of /usr/ as @John_Flatness suggests) with the following:
