Ultra+ mic not working [resolved]

#1

I installed the driver, sounds work but mic did not. Following the guide, the audio input and output did not show up on my desktop

How do i get onboard microphones to work?

When i ran below commands, i got error messages

pi@porteq:~ $ arecord -l

Hi

So I am assuming that you are using Raspbian last version, tell me if this is different.
type :

sudo dkms status

you should have exactly this showing the kernel version :
image

if not install again.

For some reason it seems to be on card 2 for you so try this

sudo arecord -D hw:2,0 -f S32_LE -r 16000 -c 2 test.wav

then

sudo aplay test.wav

#3

sudo dkms status
