While playing audio (e.g., YouTube in Firefox, native games like Chocolate Doom), the sound suddenly cuts out and is often replaced by a continuous, loud looping beep/tone. Sometimes, closing the application that was playing audio causes the looping sound to stop after several seconds, and system audio may function again temporarily before freezing again shortly after. The issue occurs reliably across all tested kernels available in the Linux Mint 22.1 repositories (6.8 series, 6.11 series). Key Evidence (Kernel Log Errors): During boot, the kernel logs consistently show errors related to the Realtek codec detection and, critically, UBSAN (Undefined Behavior Sanitizer) errors within the ALSA core's DAPM (Dynamic Audio Power Management) code during the initialization of the SOF sound card. These errors strongly suggest a kernel bug is the root cause of the instability.

Attempted disabling power saving for snd_hda_intel via modprobe.d - Ineffective (targets wrong driver component). Power save parameter for snd_sof module not found. Attempted forcing legacy audio driver via kernel parameter snd_intel_dspcfg.dsp_driver=1 - Problem persists. Checked ALSA / PipeWire / WirePlumber configurations - Appear standard (no custom user configs found). Problem occurs with different applications (Firefox/YouTube, Chocolate Doom). Expected Result: Audio playback should be stable without freezes or looping sounds. Actual Result: Audio freezes and often loops after short periods of use, associated with kernel DAPM errors during initialization. --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/seq: mijin 1242 F.... pipewire /dev/snd/pcmC0D0p: mijin 1242 F...m pipewire /dev/snd/controlC0: mijin 1242 F.... pipewire mijin 1244 F.... wireplumber CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: XFCE DistroRelease: Linux Mint 22.1 InstallationDate: Installed on 2025-03-28 (11 days ago) InstallationMedia: Linux Mint 22.1 "Xia" - Release amd64 20250110 MachineType: GOOGLE Edgar Package: linux (not installed) ProcEnviron: LANG=en_US.UTF-8 LANGUAGE=en_US PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.11.0-21-generic root=UUID=c273ba49-635f-4a9b-a1e5-e4db91a259be ro quiet splash snd_intel_dspcfg.dsp_driver=1 ProcVersionSignature: Ubuntu 6.11.0-21.21~24.04.1-generic 6.11.11 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
