No HDMI audio in Teemo (Asus Chromebox 3) i7-8550U #102

Describe the bug I'm not getting any audio out via HDMI after running the script. The HDMI audio appears as an option but there's no sound. Audio out via the headphone jack works.

I've verified the monitor/speakers work by plugging the same HDMI cable into my desktop and no issues there. I've also tried plugging into 2 different TV's with the same result.

Currently running Debian 12.5. I attempted to repro this on other distros but had various issues during install (unrelated to the audio), so I can't confirm if this is a Debian-only issue. If needed I can try the install again, let me know (along with which distro you'd prefer I try). In the process I reinstalled Debian a couple of times and each time had the same result with the HDMI audio output.

I've tried playing various sources of audio (YouTube video via Firefox, "Test Speaker" button in UI, Rythmbox radio station, etc), same results no matter the player.

I noticed in the logs that there were 3 different "HDMI" outputs listed (though only one ever appeared in the UI), so I also tried with a USB-C -> HDMI adapter dongle to see if that would change anything (no change). Finally I tried using the speaker-test CLI program which lets you direct the audio to a specific hardware output (identified via aplay -L), again no change.

Please let me know if there's any other information that might be helpful in debugging this.

Thanks for all the work you've put into this project!

I was able to get Arch linux installed and it looks like the script worked there successfully first try without any issues. Not sure what's different between the systems, but glad I got it working now.

If you would like me to do any debugging I'm happy to put Debian back on (I have an extra NVME that I can swap between), just let me know.
