There are a lot of errors about missing backend dai: [ 7.195570] Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port
So in this driver we use DPCM, which means that you have to route Front End to a BackEnd and then only you can open a device. Without linking to BE it will fail
Yes, when Liam wrote about that I started to try to understand how to find the right audio route/path, but I think it will take a while eheh :p
Thanks! So for now I tried to blindy launch these commands (apart for the "Speaker L" and "Speaker R" controls, not present in the rt5645 codec) and I got about a minute freeze at every boot and some new errors:

Yes this is a problem, which FW are you using
I am expecting you should be on http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/comm...

This is impact of FW timeout
