Audio not working on ASUS Zenbook 14 OLED (Core Ultra 7 258V – Lunar Lake)

1

Hi everyone,

I recently purchased an ASUS Zenbook 14 OLED with an Intel Core Ultra 7 258V (Lunar Lake). I am trying to install Linux, but I am facing major audio issues.

Hardware Details:

  • Laptop: ASUS Zenbook 14 OLED
  • CPU: Intel Core Ultra 7 258V (Lunar Lake)
  • RAM: 32GB
  • GPU: Integrated Intel Arc (Xe2)
  • Audio: Intel Smart Sound Technology (SST)

Linux Distribution:

  • Distro: (mention here – Fedora / Arch / Ubuntu etc.)
  • Kernel version: (output of uname -r)
  • Secure Boot: Enabled / Disabled

Problem:

  • Internal speakers produce no sound
  • Headphone jack not detected
  • Internal microphone not detected
  • aplay -l output: (paste here)
  • dmesg | grep -i audio output: (paste here)

It seems related to Intel SST / SOF firmware support for Lunar Lake. I suspect the kernel or firmware may not fully support this platform yet.

Has anyone successfully enabled audio on Lunar Lake laptops?
Is there a minimum required kernel version?
Do I need to manually install sof-firmware or apply special kernel parameters?

Any guidance would be greatly appreciated.

Thank you.
