@sjfloat:matrix.orgsjfloatIn a multiuser environement, if Mary installs a set of plugins and Joe installs another, they should be isolated.20:56:49
@sjfloat:matrix.orgsjfloatThis has no direct analog in common distros.20:57:25
@sjfloat:matrix.orgsjfloat(That occurs to me, anyway)20:57:33
@sjfloat:matrix.orgsjfloat * In a multiuser environment, if Mary installs a set of plugins and Joe installs another, they should be isolated.20:58:34
@sjfloat:matrix.orgsjfloatI guess it does in dev tools with user PMs.20:59:11

sjfloat: hmm actually i also have those installed with home-manager. lv2 and vst exist in

/nix/var/nix/profiles/per-user/yuu/home-manager/home-path/lib
``
21:14:55
@yuu:matrix.orgYuu Yin but what gets in ~/.nix-profile/ is just /nix/var/nix/profiles/per-user/yuu/profile 21:18:58
@sjfloat:matrix.orgsjfloatRedacted or Malformed Event23:04:22
@sjfloat:matrix.orgsjfloat I have ~/.nix-profile -> /nix/var/nix/profiles/per-user/steve/profile/ 23:06:40
@sjfloat:matrix.orgsjfloat The only thing I have under nix/var/nix/profiles/per-user/steve/home-manager are things pertaining to home-manager. 23:07:22
@sjfloat:matrix.orgsjfloat I have plugin directories under /home/steve/.nix-profile/lib/ 23:08:46
@sjfloat:matrix.orgsjfloat For example: /nix/var/nix/profiles/per-user/steve/profile/lib/ladspa 23:09:40

@yuu:matrix.orgYuu Yin sjfloat: for some obscure reason i don't have ~/.nix-profile/lib 01:10:48

sjfloat: which revision of home-manager are you using? do you integrate home-manager with nixos with these options?

                useUserPackages = true;
                useGlobalPkgs = true;

@eyes1238:matrix.orgeyes1238anyone here got experience with pipewire and pro audio? I know theres the snippet on the wiki https://nixos.wiki/wiki/PipeWire#Low-latency_setup but when I use that, it causes me to be unable to load or hear videos played in my browser? (firefox)03:02:28
@eyes1238:matrix.orgeyes1238I just want that low pipewire latency03:02:49
@ctem:matrix.orgctem joined the room.11:33:28
@sjfloat:matrix.orgsjfloatMy experience with that is recent -- I just switched to pipewire because that seemed to be where everything was going and because pulseaudio wouldn't build for me.13:03:05
@sjfloat:matrix.orgsjfloatI haven't gotten to the point where I've tried to reduced the latency.13:04:06
@sjfloat:matrix.orgsjfloat@yuu I'm on 20.05. I don't have HM integrated with my system config.13:05:26
@sjfloat:matrix.orgsjfloat* yuu: I'm on 20.05. I don't have HM integrated with my system config.13:06:47
@sjfloat:matrix.orgsjfloat eyes1238: Did you try tweaking the clock settings? 13:09:55
@sjfloat:matrix.orgsjfloat * I haven't gotten to the point where I've tried to reduce the latency.14:08:14
@eyes1238:matrix.orgeyes1238Not much16:03:12
@eyes1238:matrix.orgeyes1238I could probably try reducing that clock rate, but I need to find documentation for the pipewire defaults, so I know what I'm running right now16:04:16
@sjfloat:matrix.orgsjfloatThat fragment you referenced has some explicit values. If you're using that you're overriding whatever the defaults may be.16:05:17
@eyes1238:matrix.orgeyes1238No I'm not using it, I currently have unmodified pipewire settings16:19:22
@sjfloat:matrix.orgsjfloatAh, I misunderstood16:19:42
@eyes1238:matrix.orgeyes1238/etc/pipewire/pipewire.conf looks like "context.properties": { "core.daemon": true, "core.name": "pipewire-0", "default.clock.min-quantum": 16, "link.max-buffers": 16, "vm.overrides": { "default.clock.min-quantum": 1024 } 16:19:54
@eyes1238:matrix.orgeyes1238hm can you do markdown formatting over matrix16:20:05
