It looks like a recent update, likely within the Linux kernel, changed how audio Intel drivers are handled in the HP Pavilion All-in-One. Because of this, the previous workaround for audio crackling no longer works on Tumbleweed or Fedora (also in all other distros). This shift seems to have started about a year ago.
Below is the reference to the original issue and the updated fix that works now.
Old bug thread (if any mods could add the new fix there too): No sound, clicking noise - TW
New fix in 1 command:
echo “options snd-hda-intel model=generic” | sudo tee /etc/modprobe.d/audio-fix.conf
- How it works: Instead of killing the driver (blacklisting), this command keeps the driver active but changes its behavior. By setting the
modeltogeneric, you are telling the kernel: “I know you see a Realtek chip, but don’t use any of those fancy, buggy manufacturer tweaks. Just treat it like a standard High Definition Audio device.”
