soundcard with sof-firmware and Jack

[buscon]

hi,

I have a Carbon Lenovo x1 with Linux Mint and the Kxstudio mirrors.
The internal soundcard needs the sof-firmware to work, here are some references:
https://wiki.archlinux.org/index.php/Le ... n_7)#Audio
After following this guide, the soundcard works with pulseaudio but not with Jack.

When I try to start jack (using Cadence, but I get the same error using the command line), here is the error I get:

I tried to set the frames to all possible size, but I get the same error. I guess it is a driver related issue.
Maybe anyone with the same computer/soundcard managed to run jack with it?

Thanks.
