Previously in w10 it worked for me, if you connect headphones you can hear it and the microphone of the headphones works
The computer detects the sound card and even if you speak or play sound the computer frame as if it detects it (I have not disabled things in the sound panel, they are enabled)
(Cinamonn Ulyana 20)
I have tried to do things like reinstall pulseaudio but it was not solved and I have been informed that in cinammon it is dangerous to purge
I leave here more technical information:
