 gdarends | Hi all! I'm trying to configure a specific device with services.pipewire.wireplumber.configPackages but it doesn't seem like it's loading the config. I see the config file in /nix/store, but it doesn't show up in /etc.
Here is my config:
services.pipewire = {
enable = true;
alsa.enable = true;
alsa.support32Bit = true;
pulse.enable = true;
jack.enable = true;
wireplumber.enable = true;
wireplumber.configPackages = [
(pkgs.writeTextDir "share/wireplumber/main.lua.d/99-alsa-low-latency.conf" ''
monitor.alsa.rules = {
{
matches = {
{ "node.name", "matches", "alsa_input.usb-Focusrite_Scarlett_4i4_4th_Gen_S49C91841831EB-00.*"; }
{ "node.name", "matches", "alsa_output.usb-Focusrite_Scarlett_4i4_4th_Gen_S49C91841831EB-00.*"; }
},
apply_properties = {
["audio.rate"] = 192000,
["api.alsa.period-size"] = 512,
["api.alsa.period-num"] = 3,
},
},
}
'')
];
# add virtual audio device for butt streaming
extraConfig.pipewire = {
"99-clock-rates" = {
"context.properties" = {
"default.clock.allowed-rates" = [ 48000 192000 ];
};
};
};
};

| gdarends | I'm using this guide: https://nixos.wiki/wiki/PipeWire#Controlling_the_ALSA_devices | 14:16:48 |
 @raf:notashelf.dev |
- nixos.wiki is outdated, don't use it
- you will need to put keys in quotation marks, e.g.,
"monitor.alsa.rules" instead of monitor.alsa.rules
| 14:17:23 |
| gdarends | But the guide specifically mentions 24.05 | 14:19:04 |
| @raf:notashelf.dev | the guide is wrong, then | 14:19:31 |
| gdarends | Ok | 14:19:52 |
| @raf:notashelf.dev | the bluetooth section looks correct | 14:19:55 |
| @raf:notashelf.dev | ALSA low latency section is not | 14:20:01 |
| gdarends | So correct me if I'm wrong. This config is not being published because the syntax is wrong? | 14:21:45 |
| @raf:notashelf.dev | not quite | 14:22:08 |
| @raf:notashelf.dev | you are using extraPackages, iirc that does not get linked to /etc | 14:22:16 |
| gdarends | It is building and it is populating in /nix/store | 14:22:18 |
| @raf:notashelf.dev | * you are using configPackages, iirc that does not get linked to /etc | 14:22:29 |
| gdarends | I did a find / and I can't find it anywhere. | 14:23:33 |
| gdarends | I updated my config, but it's still not being loaded. I tried both configPackages and extraConfig. None work.
wireplumber.configPackages = [

 kjeremy | How do I set my flake's inputs.nixpkgs to be from another flake input as in inputs.b.nixpkgs? | 17:29:15 |
| kjeremy | I was thinking something like nixpkgs = b.inputs.nixpkgs but that doesn't work | 17:30:53 |
 mewp | .follows | 17:31:18 |
| mewp | for example inputs.nixops.inputs.nixpkgs.follows = "dwarffs/nixpkgs"; | 17:32:50 |
| kjeremy | I understand that that's how you set the nixpkgs of nixops but I'm trying to set the top-level nixpkgs | 17:33:56 |
| kjeremy | ah i think i got it.thank you. the "/" was the key | 17:34:52 |

| hellwolf | How should "overlays.default" in a flake actually be used?
I try to use it in another flake. But I got "error: attribute 'overlay' missing" | 13:57:43 |
| hellwolf | overlays = [
solc.overlays.defaul # <-- ?
];
| 14:00:52 |
| hellwolf | {
description = "A very basic flake";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
flake-utils.url = "github:numtide/flake-utils";
};
outputs = { self, nixpkgs, flake-utils }:
flake-utils.lib.eachSystem
[
"x86_64-linux"
"x86_64-darwin"
"aarch64-darwin"
] (system:
let packages = import nixpkgs {
inherit system;
# overlays = [ solc-pkgs-overlay ];
};
in
{
inherit packages;
});
}
And what's wrong with this flake...
| 16:05:26 |
| hellwolf | Nix flake check complains:
error: flake attribute 'packages.x86_64-linux.system' is not a derivation
| 16:08:17 |
| hellwolf | Ah, that should be legacyPackages | 16:09:16 |
