System: Pixelbook Go (2019?) running Debian 12 installed following these instructions: https://docs.mrchromebox.tech/docs/getting-started.html.
Issue: No Audio through speakers/headphone jack (I understand this OS is not supported on this device, however I am still trying to find solution.) Only getting Dummy Audio.
Workaround: USB interface does work.
Troubleshooting:
Per https://docs.chrultrabook.com/docs/installing/installing-linux.html#fixing-audio
# git clone <https://github.com/WeirdTreeThing/chromebook-linux-audio.git>
# cd chromebook-linux-audio
# ./setup-audio
Error: receiving multiple Warning: Kernel is missing module 'SND_SOC_INTEL_AVS' messages
Attempts:
# sudo apt update && sudo apt install -y firmware-sof-signed
firmware-sof-signed is already the newest version (2.2.4-1).
# echo "options snd-hda-intel model=generic dmic_detect=0" | sudo tee /etc/modprobe.d/alsa-base.conf
# echo "blacklist snd_soc_avs" | sudo tee /etc/modprobe.d/blacklist-avs.conf
# sudo update-initramfs -u
After reboot, I received Digital Stereo (HDMI) Output within Volume Control GUI. Still no speaker or headphone jack output.

# sudo nano /etc/default/grubFind
added snd_hda_intel.dmic_detect=0 to GRUB_CMDLINE_LINUX_DEFAULT=”quiet”
# sudo update-grub
Getting interesting new Debian 12 splash screen at boot, but issue not resolved.
alsamixer shows 00
Any guesses that I’m missing?
