Hi Liam,

Thanks a lot for your answer. Still one question inline:

So, I think I have setup everything correct (btw I use SOF modules
builtin in the kernel image, because I find it easier).

Anyhow, I expect that the function sof_probe from sound/soc/sof/core.c
to be called but it isn't :).

Any idea why?

Now, this function should be called as a result of a platform device
named "sof-audio" being somehow registered.

thanks,
Daniel.
