Microphone not working on Lenovo Yoga 7 Gen 7 AMD (14ARB7)

[Saverio Miroddi]

On my Lenovo Yoga 7 Gen 7 AMD (14ARB7), the microphone doesn't work. I'm not familiar with the area, but I think that there is no recognized input device at all.

When I try to record with any program, no sound is recorded.

I think that this problem affects other Lenovo Yoga laptops.

This patch:

    https://bugzilla.kernel.org/show_bug.cgi?id=216299#c3

fixes the problem. The volume is low, but better than not working at all :)
