Can you provide exact notebook brand type etc?

In My Lenovo P53 and HP env 17 and Lenovo P1 sounds works without any issues.

I use below config in my configuration.nix

    pulseaudio = {
      enable = true;
      support32Bit = true;
      package = pkgs.pulseaudioFull;
    };

  sound.enable = true;

  nixpkgs.config = {
    pulseaudio = true;
    allowBroken = true;
    allowUnfree = true; 
  };

Full config for Lenovo P53 you can find

My notebook is Itautec Infoway Note w7430
