Title:
Microphone not working on Lenovo Yoga 7 Gen 7 AMD (14ARB7)
Status in alsa-driver package in Ubuntu:
New
Bug description:
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.
