No sound on ASUS T100HA

[OCMan2K]

Hello, first of all thank you for your great work, it is awesome!!!
I am trying to install ThoriumOS on Asus T100HA-FU006T wich is Bay trail z8500 based.
All is working great except brightness, screen off when idle, autorotation and audio.
The biggest problem for me is audio,
seems detected (even if I plug a headphone i can choose headphone or internal speaker, but no sound at all.
I searched on the sofproject page, and found this :

WARNING: starting with v2.2, older Intel products are not supported by the main SOF development branch anymore. To avoid duplication and confusion in this sof-bin git repository, older product generations are now intentionally MISSING from sof-bin subdirectories v2.x/sof-v2.2/ and above.

For a complete release that includes all Intel products including older ones you MUST use official release tarballs found here:

https://github.com/thesofproject/sof-bin/releases

Installing directly from the sof-bin git repo should still work but it will only install a subset.

Tarballs are now a combination of several sof-bin subdirectories generated by a new release script. They include a new manifest.txt describing that combination. For more details see Github issue #90.

Maybe you could make a special version of ThoriumOS for these old baytrail/cherrytrail platform because they could have a second life with your OS wich is great!!!
Thank you so much

PS : sound working perfectly in cloudready v96 (latest version before chromeflex)

managed to install kubuntu 23.04 and have all working except webcam, for sound to work without problem, i needed to add this conf to grub : intel_idle.max_cstate=2 and disabled intel_iommu
and options snd-intel-dspcfg dsp_driver=2 at the end of my /etc/modprobe.d/alsa-base.conf

don't know how to do this in thoriumOS
Maybe it can help you. thanks.

@OCMan2K That actually is helpful. I might downgrade the sof-firmware package, and add alsa configs for this. However, for the alsa configs, I need to know more about your device. Because we only want the config being applied for specific hardware that needs it. Having it just always be applied, or applied to a large subset of devices (for example if I set it to always use it if it detects baytrail), will break other configurations.

If I cant do the alsa thing for whatever reason, I can at least try to fix the firmware, and then you could mount the rootfs read/write (which I actually added a handy alias for in the shell, simply run fs (i guess i named it for filesystem?), and then set up your configs similar to how you did Kubuntu.

Also, since V117, ThoriumOS has been based on the "reven" overlay, which is the open source counterpart to ChromeOS Flex (RIP Neverware, Cloudready, and the Cloudready forums, so sad. I FUCKING KNEW that when Google bought them it was going to be a developer non-friendly, money grabbing shit-show). If you can install ChromeOS Flex V120 on this chromebook and sound or other things you mentioned work fine, then that lets me know it is something on my end that I need to fix.

I really don't know how to help much with my device, tell me how to acces the shell ( only tried thorium as guest, maybe I must have a real account to acces console )
I can confirm that on Revel build based chromeflex, audio doesn't work either, it only worked in the latest cloudready build.

hi, I can confirm that sound still not working on the latest version with Asus T100HA.
However, if you can help me a bit with step by step, I am okay to help, I had a heavy motorcycle crash last week , and I am locked at home for at least a month :(
also sound doesn't work vith headphone jack, even if correctly detected
