Hi everyone,

I'm struggling to get audio working on my Chuwi HeroBook Pro (Intel Celeron N4020 / Gemini Lake) running Zorin OS 18.

The Problem: I've gone from "stuttering audio" to "Dummy Output" and sometimes no output device detected at all.

Hardware Details:

• Audio Chip: ES8336 (ESSX8336)
• CPU: Intel Celeron N4020
• DSP Driver: snd_sof_pci_intel_apl

What I've tried so far:

1. Set options snd-intel-dspcfg dsp_driver=3 in modprobe.
2. Tried different quirks for snd_soc_sof_es8336 (quirk=0x01 and quirk=0x04).
3. Verified firmware: The system looks for sof-glk-es8336-ssp2.tplg but I suspect there's a mismatch or missing topology file.
4. dmesg shows: ASoC: Parent card not yet available, widget card binding deferred.
5. Alsamixer shows the card when it's not in "Dummy Output", but even with everything unmuted, there's no sound.

Current Status: I'm currently stuck on "Dummy Output". I've updated initramfs after every change.

Is there a specific UCM configuration or a kernel parameter I'm missing for this specific laptop? Any help would be appreciated before I consider moving back to Windows.

Thanks!
