Same problem on Lenovo IdeaPad 310-15IKB, ubuntu 19.10 with kernel 5.3.0-46.

@David Henningsson (diwic): we haven't heard from you on this bug in

Sorry to necro such an old thread but there seems to be a regression. I
have this same issue on my Lenovo Ideapad 320s. Given that it seems
almost unique to Lenovo, would it be possible to create a general case
for all Lenovo laptops where muting one internal microphone is an option
by default?
It seems that Lenovo Yoga 300 also has the same problem. I reported Bug
#1713784.
