Realtek Audio sound card not recognized by pipewire

I am new to Nixos and I am not able to get any audio from my Acer laptop. Digging a little deeper it seems that while the audio card comes up in hardware info, it seems to not be recognized by some of the audio driver packages. I’ve tried alsa, pipewire, pulseaudio.

Is there some configuration I need to do in order for pipewire to work? Or possibly some special firmware?

Thank you for your time!

Nix Configuration:

  # Enable sound with pipewire.
  sound.enable = true;
  hardware.pulseaudio.enable = false;
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    # If you want to use JACK applications, uncomment this
    jack.enable = true;
    
    # use the example session manager (no others are packaged yet so this is enabled by default,
    # no need to redefine it in your config for now)
    #media-session.enable = true;
  };


  environment.systemPackages = with pkgs; [
    alsa-firmware
    alsa-oss
    alsa-lib
    alsa-utils
    alsa-tools
    alsaequal

Solution is to add a kernel param.

Depreciated version:

boot.kernelParams = [ "snd_hda_intel.dmic_detect=0" ];

Current version:

boot.kernelParams = [ "snd-intel-dspcfg.dsp_driver=1" ];

Based on this arch forum post: https://bugs.archlinux.org/task/64720
