@CEDO @janneke @tdose Ah yes, such chromebooks also use sound cards that are handcuffed to only run proprietary software ((mostly) source-available, developed under an "open source" development model and released under a free license, but it is not free software, as you cannot run a free version on the only computer you want to run it on.

If you want to make a change, you need to purchase an expensive handcuffed SBC, except the sound card doesn't happened to be handcuffed and do gratis work for intel and beg them to sign a binary containing your modifications - but that binary may not even end up working, as chances are the chipset is slightly different as to what's in the chromebook.

The result is that the sound card does not work and you can't fix it.
