Intel's Sound Open Firmware

I haven't heard about a need for a sound card firmware until I got the new ThinkPad T14 gen.2

This announcement about support by Linux kernel is 2+ years old.
This is the project itself: sofproject.org.

1. Is it right that certain sound devices won't work properly without firmware?
2. Are there any considerations about supporting this in FreeBSD?

Thanks!
 
I need to install intel soundcard firmware for my older soundcard to work correctly in Linux for instance debian, void-linux or alpine-linux.
I think it needs some blobs. How my soundcard works with freebsd i don't know but it works. I think also some blob data is in the drivers.
 
Currently my T14's microphone doesn't work in FreeBSD.
In a Live Devuan it doesn't work either, probably because it doesn't supply firmware on the live CD.
 
1 year late but I'm here I have a Chromebook possibly needs the sof-firmware to get sound working. Here is my problem. Please let us know what the outcome of your porting or progress is

I've installed Linux all kind of distros and sof-firmware is needed

Thanks
