thinkpad_acpi: disagreement about versions

thinkpad_acpi: disagreement about versions

[Dirk Gouders]

Hello,

after a longer time not using Zoom, I was asked to have a Zoom meeting
with some colleague and recognized, my mic isn't working (I'm using
Gentoo).

Chances are high, I'm doing something wrong with ALSA or PulseAudio.
These things usually just worked and I cannot preclude that I did
something wrong without noticing that I "killed" my mic.
But during the pandemic, I had several Zoom meetings and no problems --
with a recently replaced thinkpad, however.

I'm always running some recent kernel built from Linus' development
branch and now noticed these messages:

[    4.943230] thinkpad_acpi: disagrees about version of symbol snd_ctl_add

I'm still gathering information and trying to get more understanding but
maybe someone could give me a hint where to look or to ask questions if
I don't get any further.

Thanks,

Dirk
