| Guillaume Desforges | * pipewire with jack enabled on NixOS | 08:58:48 |
 @tamtaram:chat.heizhaus.org | I'd recommend you give a go at a pipewire native GUI tool and not qjack since that's not interacting with pipewire's native Api afaik | 09:00:28 |
| @tamtaram:chat.heizhaus.org | Check out this ;)
https://github.com/mikeroyal/PipeWire-Guide#audio-tools--libraries-to-use-with-pipewire | 09:00:32 |
| @tamtaram:chat.heizhaus.org | qpwgraph is basically qjackctl for pipewire | 09:01:06 |
| @tamtaram:chat.heizhaus.org | Hope u get it to worj | 09:03:24 |
| @tamtaram:chat.heizhaus.org | * Hope u get it to work | 09:03:29 |
 Minijackson | I personally use pw-viz, which is already packaged in nixpkgs | 09:03:59 |

slightly unrelated
i've added an effect in easyeffects, it crashed, and now no longer starts
(killed, returns 137)
i've not found the local config for that, so it seems like i can't undo adding the effect
and maybe related, audacity takes forever to start, but starts in a pure nix-shell FYI: easyeffects -r resets it (still crashes on that invocation), that fixed it | 12:41:59 |

still waiting for audacity to launch though xD | 12:43:06 |
| evils | anyone know how to set the sample rate in pipewire? | 13:47:28 |
| Minijackson | In reply to @evils:nixos.dev
anyone know how to set the sample rate in pipewire? maybe you can using the PIPEWIRE_LATENCY env variable, but it's per-client | 17:59:30 |
| Minijackson | for example PIPEWIRE_LATENCY=256/48000 carla | 17:59:36 |
| evils | yea, i found that, it does nothing | 18:00:01 |
| evils | i did set a /etc config file that may take effect the next time i reboot, but i'm hoping not to reboot for a while | 18:00:39 |

yea, i found that, it does nothing it did help me for the "latency" part | 18:01:02 |
| Minijackson | In reply to @evils:nixos.dev
i did set a /etc config file that may take effect the next time i reboot, but i'm hoping not to reboot for a while a pipewire config file? What did you put, if I may ask? | 18:01:37 |
| evils | environment.etc = let
json = pkgs.formats.json {};
in {
"pipewire/pipewire.d/92-low-latency.conf".source = json.generate "92-low-latency.conf" {
context.properties = {
default.clock.rate = 192000;
default.clock.quantum = 32;
default.clock.min-quantum = 32;
default.clock.max-quantum = 1024;
};
};
};
| 18:02:00 |
| evils | basically directly from the NixOS wiki but with my interface's max sample rate | 18:02:29 |
| Minijackson | thanks | 18:02:37 |
| Minijackson | if you don't want to reboot, you could just restart pipewire | 18:03:19 |
| evils | i somewhat suspect it's up to users of a sink to request a sample rate
as the inverse is the case (if i play a high sample rate file, pw-top shows it as high sample rate) | 18:03:39 |
| evils | In reply to @Minijackson:matrix.org
if you don't want to reboot, you could just restart pipewire how? | 18:03:46 |
| evils | Failed to restart pipewire.service: Unit pipewire.service is masked. | 18:04:03 |
| Minijackson | systemctl --user restart 'pipewire*' should do the trick | 18:04:08 |
| Minijackson | In reply to @evils:nixos.dev
Failed to restart pipewire.service: Unit pipewire.service is masked. yeah, it's a user service, not a system service | 18:04:37 |
| evils | easyeffects still reports 48kHz sample rate | 18:05:34 |
| Minijackson | In reply to @evils:nixos.dev
i somewhat suspect it's up to users of a sink to request a sample rate
as the inverse is the case (if i play a high sample rate file, pw-top shows it as high sample rate) I think it's like gstreamer, where the sample rate may be negotiated between clients | 18:05:57 |
| evils | ardour also gets 48kHz, and i can't configure the sample rate in that, it's up to jack, and qjackctl is already set to 192kHz
it does jack shit (pardon the pun) | 18:06:59 |
| Minijackson | I started carla with PIPEWIRE_LATENCY=256/192000 | 18:09:05 |
