Comment 33 for bug 1845797

I've recently upgraded to latest Lenovo Yoga S940, with Intel Core 7 10th gen.
With Focal Fossa, both audio and mic worked properly until a few days ago.

Now *sometimes* it loads with dummy audio and no mic at all.
Now it loaded with only audio and no mic.

It really seem random to me now.

There is this question that despite a different laptop, has a very similar config:

In fact my outputs are:

5.4.0-31-generic

Codec: Realtek ALC298
Codec: Intel Icelake HDMI

00:1f.3 Multimedia audio controller: Intel Corporation Smart Sound Technology Audio Controller (rev 30)
