You have been subscribed to a public bug: Since installing Zorin OS (based on Ubuntu Jammy), I have no audio functionality on my INSYS 11.6p GW1-W116 N4020 laptop. Despite extensive troubleshooting, the kernel consistently reports "Unknown kernel command line parameters" for various boot options, which appears to be preventing the Sound Open Firmware (SOF) audio driver from fully initializing.
Problem Details: No Audio Output: aplay -l consistently reports "no soundcards found..." (nenhuma placa de som encontrada...). alsamixer also fails to open, stating "cannot find card '0'". Kernel Command Line Parsing Error: The primary symptom in dmesg is the persistent error message: Unknown kernel command line parameters "splash sof_debug BOOT_IMAGE=/boot/vmlinuz-6.8.0-XX-generic", will be passed to user space. This error occurs regardless of how the parameters are set (via GRUB, manual GRUB edit, or modprobe options) and even affects fundamental parameters like "splash" and the BOOT_IMAGE path. Hardware: Laptop Model: INSYS 11.6p GW1-W116 N4020 Processor: Intel Celeron N4020 (Gemini Lake Refresh) Audio Controller: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio [8086:3198] Audio Codec: ESSX8336 (Everest Sound Device, I2S codec) Firmware Version: EM-IG218_v2.0.8 (from DMI info) Kernel Versions Tested: 6.8.0-59-generic (initial and reinstalled) 6.8.0-57-generic (older version, tested from GRUB advanced options) The issue persists identically on both kernel versions. Troubleshooting Steps Already Performed: Modified /etc/default/grub: Set GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_intel_dspcfg.dsp_driver=1 sof_debug". Updated GRUB: Ran sudo update-grub multiple times. Manual GRUB Edit at Boot: Edited the linux line at GRUB menu (E key) to ensure correct spacing and parameters (ro quiet splash snd_intel_dspcfg.dsp_driver=1 sof_debug). The dmesg command line confirmed the edit was applied, but the "Unknown parameters" error persisted. Reinstalled Kernel: Reinstalled linux-image-6.8.0-59-generic, linux-modules-6.8.0-59-generic, and linux-headers-6.8.0-59-generic via sudo apt install --reinstall. Forced Module Option: Created /etc/modprobe.d/snd_intel_dspcfg.conf with options snd_intel_dspcfg dsp_driver=1, then ran sudo update-initramfs -u -k all. Checked BIOS/UEFI Settings: Confirmed there are no specific "OS Type" or "Audio Type" settings, and integrated audio is enabled. alsa-info.sh analysis: Showed that relevant SOF modules (snd_sof, snd_sof_pci_intel_apl, snd_soc_es8316, snd_intel_dspcfg, etc.) are listed as loaded, but ALSA still reports no sound cards, indicating modules are loading but not successfully initializing the hardware.
