Asked by pdg

Hello, as the title suggests, I have a chuwi herobook pro with dual boot windows and ubuntu 22 installed.
My problem is that with ubuntu the sound does not work while if I start windows it works regularly.

Thanks for the reply
the sound from the speakers and earphones does not work, I only have the dummy output.

Can you help with this problem?
