Hello all!
This is my first post here 
I just installed Manjaro Gnome on an old ThinkPad 13 Chromebook and I am experiencing issues with the soundcard’s firmware.
Here’s what I get in the journal:
snd_soc_skl 0000:00:1f.3: Direct firmware load for 9d70-CORE-COREBOOT-0-tplg.bin failed with error -2

skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -2
I have placed the firmware under /lib/firmware/ and I even tried to use both expected filenames without success.
Getting audio to work on this device is tricky, but I know for sure that it works with Arch Linux. I suspect this is related to the kernel, although it would be nice if somebody more knowledgable than me can point me to the right direction.
Thank you all in advance.
