Lunar Lake audio broken on Fedora 43 – headphone jack initially, now all audio (Dummy Output)

Hi everyone,

I’m new to Fedora and Linux, so apologies if I’m missing something obvious.

I’m on Fedora Workstation 43 running on an Intel Lunar Lake laptop.
Initially, my headphone jack was not working (headphones detected but no sound). Speakers worked at that time.

After troubleshooting and system updates, the situation has worsened:

  • Now no audio works at all (neither speakers nor headphone jack)
  • The sound settings only show “Dummy Output”
  • Volume changes do nothing

What I’ve tried so far:

  • Updated the system fully
  • Booted into older kernels that previously worked (6.17.x), but audio is still gone
  • Reset PipeWire / WirePlumber configs
  • Reinstalled audio packages
  • Fedora Live USB previously had working audio
  • Followed extensive troubleshooting with ChatGPT, but no success

Current state:

  • Fedora Workstation 43
  • Intel Lunar Lake
  • Kernel hopping between 6.17.x and 6.18.x
  • aplay -l previously showed devices, now user-facing audio is “Dummy Output”

At this point I’m stuck and not sure what to do.

Any guidance on how to recover audio, or what logs / commands I should provide, would be greatly appreciated.

Thank you for your time and help.
