[Bug 2127117] Re: [Asus Zenbook UX425QA_UM425QA] No codecs found for the internal sound card, resulting in a 'Dummy Output' device.
My /etc/modprobe.d/alsa-base.conf is empty. Still nada. Also, I think
it's relevant: the issue was still happening when i changed distros:
initially, I had Linux Mint and the issue kinda transferred over?
** Description changed:
Dear Sirs or Madams,
I am writing to tell you about an extremely devastating issue that has
- been bothering throughout these couple of weeks. am reporting an issue
+ been bothering throughout these couple of weeks. I am reporting an issue
where the internal audio hardware (speakers and headphone jack) is not
detected on my ASUS laptop. The system consistently falls back to a
"Dummy Output" device, and no sound is produced. I had it "fixed" a
couple or times by a cold boot and installing a package with sudo apt
install linux-oem-24.04, but it still returned to "Dummy Output" after a
while.
To provide system info:
Laptop Model: ASUS Zenbook UX425QA
Distribution: Ubuntu 24.04 (or based on it)
Kernel Version Tested: 6.14.0-33-generic (also occurred on
6.14.0-1013-oem)
Hardware Info (from lspci -k):
04:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Renoir Radeon High Definition Audio Controller
- Kernel driver in use: snd_hda_intel
+ Kernel driver in use: snd_hda_intel
04:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] ACP/ACP3X/ACP6x Audio Coprocessor
- Kernel driver in use: snd_rn_pci_acp3x
+ Kernel driver in use: snd_rn_pci_acp3x
04:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h/19h HD Audio Controller
- Kernel driver in use: snd_hda_intel
+ Kernel driver in use: snd_hda_intel
The primary issue seems to be that the snd_hda_intel driver fails to
find the audio codec for the analog output device. The key error message
in dmesg is:
snd_hda_intel 0000:04:00.6: no codecs found!
This is accompanied by a user-space error from WirePlumber, which fails
to initialize the AMD Audio Co-Processor:
wireplumber: SPA handle 'api.alsa.acp.device' could not be loaded; is it installed?
wireplumber: Failed to create 'api.alsa.acp.device' device
I have already taken many steps to resolve the issue, without success:
- Updated the laptop's BIOS/UEFI to the newest version available from the ASUS support website.
- Performed a full system update (apt update && apt upgrade).
- Ensured the latest linux-firmware, sof-firmware, and alsa-ucm-conf packages are installed.
- Tested both the OEM kernel and the newer generic HWE kernel provided by Ubuntu. The issue persists across all versions.
- Removed any custom audio-related kernel boot parameters.
The issue seems to be a driver-level incompatibility with this specific
hardware implementation.
I am happy to provide full dmesg logs, lspci -vvv output, or any other
information required to help diagnose and resolve this bug.
Thank you for your time and work on the Linux kernel.
Sincerely,
Vic (They/She)
