vocal assistent google

[disegnoarch]

Hi everyone, after installing ROSA 11 on a LENOVO V145-15AST laptop, the only problem I have, which I can't solve, is the google voice assistant.
I chose this distro because on my ASUS-55A laptop (the LENOVO laptop would be for a person who asked me to install a decent operating system on it), the google voice assistant works perfectly.
I also tried trying to install several audio plugins and try to install the same audio packages that are on the ASUS laptop, but to no avail.
I noticed however that in pulse audio the slide of the microphone moves when I speak but it vibrates continuously and doing a test with VLC / KAMOSO / CHEESE does not record.
I also tried many combinations of PULSEAUDIO but with no results.
Is it possible that the laptop needs some particular driver or someone knows what is the correct combination of audio plugins, or at least, how to test if there are plugins that do not allow the voice assistant to work?
Ciao
Pietro
