@mcdonc:matrix.orgChris McDonoughbut isnt the whole point of pipewire to explicitly not need to suspend anything17:36:05
@sjfloat:matrix.orgsjfloatThat's part of it, yes.17:36:20
@sjfloat:matrix.orgsjfloatBut the two modes are really pretty divergent. I think trying to reconcile them into a single config creates unnecessary tension.17:37:23
@sjfloat:matrix.orgsjfloatI don't need or probably even want real time config in my normal desktop.17:37:44
@sjfloat:matrix.orgsjfloat(as an example)17:37:51
@mcdonc:matrix.orgChris McDonoughi'm a little suspicious of anyone needing that realtime stuff these days17:38:49
@mcdonc:matrix.orgChris McDonoughi mean, macos doesn't have it, and most folks who do pro audio work use macs17:39:05
@sjfloat:matrix.orgsjfloatIt's pretty common on for people doing pro audio on linux to manipulate it trying to get latency down to what they want.17:40:53
@sjfloat:matrix.orgsjfloathttps://github.com/musnix/musnix17:41:39
@mcdonc:matrix.orgChris McDonoughi mean, i'm sure there are some useful realtime settings you can tweak, but nobody needs a custom kernel anymore17:41:47
@sjfloat:matrix.orgsjfloat * It's pretty common for people doing pro audio on linux to manipulate it trying to get latency down to what they want.17:41:59
@sjfloat:matrix.orgsjfloatNo, I agree.17:42:10
@mcdonc:matrix.orgChris McDonoughmaybe not nobody, but not me anyway :)17:42:14
@sjfloat:matrix.orgsjfloatAnd probably not for low latency.17:42:30
@mcdonc:matrix.orgChris McDonoughi have all those musnix rtc things set up in my config and i don't notice any ill effect17:43:06
@mcdonc:matrix.orgChris McDonoughi think your thing with chrome you gotta dig into; i use firefox or i would help17:43:42
@sjfloat:matrix.orgsjfloatThe thing that's troubling me right now is that, having switched to pipewire, my browser is really struggling -- almost unusable sometimes.17:44:09
@mcdonc:matrix.orgChris McDonoughi cant say ive noticed any difference in firefox since i switched to pipewire.. still plays youtube fine without undue struggle, etc17:44:37
@sjfloat:matrix.orgsjfloatAnother things is that I'd like to run dedicated audio things on rpi where I'll be trying to squeeze all the performance I can out of it. 17:46:13
@sjfloat:matrix.orgsjfloatI'd like to be able to do that with NixOS.17:46:22
@sjfloat:matrix.orgsjfloatAnd some of my gear is old.17:46:53
@mcdonc:matrix.orgChris McDonoughwell, maybe one thing to try is that, like, youtube has "stats for nerds" when you play a video17:46:57
@mcdonc:matrix.orgChris McDonoughmaybe just see what that says under firefox vs chrome?17:47:09
@sjfloat:matrix.orgsjfloatIt's not limited to while I'm playing youtube. 17:47:22
@mcdonc:matrix.orgChris McDonoughsure, its just a useful profiling tool17:47:40
@sjfloat:matrix.orgsjfloatAt any rate, I have need of a configuration with neither pipewire nor pulseaudio. 17:48:24
@sjfloat:matrix.orgsjfloat I need to work out what the minimal audio config is in configuration.nix. The rest I'd like to do at the user level. 17:49:18
@sjfloat:matrix.orgsjfloat There are jack-related tools that I use that will likely never work with pipewire. 17:50:04

@mcdonc:matrix.orgChris McDonoughhere's what i see under chrome with pipewire17:50:07
