So just to verify, you get the same result if your remove these lines from /etc/modprobe.d/alsa-base.conf
options snd-hda-intel single_cmd=1 options snd-hda-intel probe_mask=1 options snd-hda-intel model=basic Correct? ** Summary changed: - No audio codecs are found for the internal sound card, resulting in a 'Dummy Output' device. + [Asus Zenbook UX425QA_UM425QA] No codecs found for the internal sound card, resulting in a 'Dummy Output' device. ** Package changed: ubuntu => alsa-driver (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/2127117 Title: [Asus Zenbook UX425QA_UM425QA] No codecs found for the internal sound card, resulting in a 'Dummy Output' device. Status in alsa-driver package in Ubuntu: New Bug description: 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 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 04:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] ACP/ACP3X/ACP6x Audio Coprocessor 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 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.
