hwinfo output (hwinfo run under kernel 5.9.14)

With kernel 5.10.x, only sound output over headphones (3.5mm plug) works on my
laptop.

The following things do NOT work:
- internal microphone
- microphone input (3.5mm plug)
- internal speaker

This happens with all 5.10.x kernels Tumbleweed got so far (starting at 5.10.1,
and still in 5.10.7).

kernel-default-5.9.14-1.2.x86_64 (and older) have working sound, therefore I
boot with 5.9.14 as a workaround.

Hardware: a laptop with Intel CPU, graphics and sound chip. The output of
hwinfo is attached.

If you need more information or want me to test something, just ask ;-)
