@Minijackson:matrix.orgMinijackson do you have any systemd.sockets.pipewire-pulse.<...> option set? 15:38:08
@Minijackson:matrix.orgMinijackson or have you overridden the pipewire package in an overlay? 15:40:35
@industrial:matrix.orgIndustrial

I had a previous installation of nixos and while learning nixos I started to create a flake to manage my system. Unfortunately I left some artifacts on the system state and I couldn't figure out what was wrong so I reinstalled nixos today to have a clean slate.

This is the flake.nix file that I'm using:

https://gist.github.com/Industrial/9646bc7f66d21ae7f78a85bff040cd10

The HomeManager setup does not contain any audio configuration

15:43:14
@industrial:matrix.orgIndustrial(the problem I was having before was not about sound but stuff like yggdrasil service running but not in my config and lots of other quirks)15:43:54
@Minijackson:matrix.orgMinijackson Industrial: ok, so I built the etc directory of your configuration, and I do have ./result/etc/systemd/user/pipewire-pulse.socket -> /nix/store/cg5412y1xdp5nl2sfmh62h5g9hvkibvp-pipewire-0.3.70-pulse/lib/systemd/user/pipewire-pulse.socket 15:57:32
@Minijackson:matrix.orgMinijacksonand the correct content15:57:52
@Minijackson:matrix.orgMinijackson mind showing nix flake metadata of your flake? 15:58:04
@Minijackson:matrix.orgMinijackson(I just commented the import, and the wine package due to compilation)15:58:49
@Minijackson:matrix.orgMinijackson * (I just commented the import, and the wine packages due to compilation)15:58:59

@Minijackson thanks for the support/effort :)

@Minijackson:matrix.orgMinijacksonhuh16:23:57
@Minijackson:matrix.orgMinijacksonoh nevermind16:24:25
@Minijackson:matrix.orgMinijacksonsame thing16:24:34
@industrial:matrix.orgIndustrial pipewire-pulse.socket -> /nix/store/cg5412y1xdp5nl2sfmh62h5g9hvkibvp-pipewire-0.3.70-pulse/lib/systemd/user/pipewire-pulse.socket that's in my result 16:24:38
@Minijackson:matrix.orgMinijackson does nixos-rebuild test say something in particular? 16:25:07
@industrial:matrix.orgIndustrialIt also contains a config, that socket file16:25:42

16:26:22
@industrial:matrix.orgIndustrialoh sudo16:26:39
@industrial:matrix.orgIndustrial I think that this command sets up the /etc/nixos/configuration.nix again, so it doesn't have my flake config 16:27:35
@Minijackson:matrix.orgMinijacksonoooh, that would explain the difference16:27:52
@Minijackson:matrix.orgMinijackson you can use nixos-rebuild --flake '.#drakkar' 16:28:18

@Minijackson:matrix.orgMinijackson is /etc/systemd/user/pipewire-pulse.socket correct now? 16:30:05
@industrial:matrix.orgIndustrial

hmm, it contains

[Unit]
Description=PipeWire PulseAudio
ConditionUser=!root
Conflicts=pulseaudio.socket

[Socket]
Priority=6
ListenStream=%t/pulse/native

[Install]
WantedBy=sockets.target

That's the same as in the built result

16:34:31
@Minijackson:matrix.orgMinijacksonI think that was the issue then16:35:01
@industrial:matrix.orgIndustrialI restarted the socket and it works now. But what was the issue?16:35:20
