Internal Audio (Speakers/Mic) not detected - ASUS Zenbook S 16 (UM5606GA) - Ryzen AI 9 465 - Fedora 44

Hi everyone,

I need help with an internal audio issue on the new ASUS Zenbook S 16 (UM5606GA). Neither the internal speakers nor the microphone are detected by the system.

System Environment:

  • Laptop: ASUS Zenbook S 16 UM5606GA
  • CPU: AMD Ryzen AI 9 465 (Strix Point)
  • OS: Fedora Linux 44 (KDE Plasma Edition)
  • Kernel: 7.0.4-200.fc44.x86_64

The Problem:

  • aplay -l does not list any internal soundcards (only HDMI/DP).
  • Bluetooth and HDMI audio work perfectly.
  • The sound system is powered by ACP 7.0, but it fails to initialize.

Relevant dmesg logs: The most critical error seems to be a missing machine driver match for this specific CPU/Laptop combo: [ 7.166367] platform acp_asoc_acp70.0: warning: No matching ASoC machine driver found

I also have several ACPI BIOS errors during boot: ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.GPP4._S0W], AE_ALREADY_EXISTS

What I have tried:

  • Updated to the latest BIOS available from ASUS.
  • Tested several kernel parameters: acpi_quirk_skip_dsd, and snd_pci_acp6x.dmic_acp_check=1. None of them worked for the audio.
  • Verified that alsa-sof-firmware is installed.

It seems the Ryzen AI 9 465 variant is not yet correctly mapped in the acp_asoc_acp70 driver.
