Comment 55 for bug 1892714

The sof-cfl.ri file you attached in #46 is needed on my machine (to be able to run without dmic_detect=0). With this file and without dmic_detect=0 internal speakers and internal mic work. They are shown in Sound settings as described in #23. (Plugged jack headphones and mic also work).

I tested both with 5.4.0-42-generic and with 5.9.0-rc2+ kernels. The behavior is the same.

Now I should note. I use Intel GPU currently in both of these kernels! The kernel 5.8 does use Nvidia GPU with Nouveau drivers, but with that kernel the sound nor the mic don't work.
