 Miles Dyson | I was just reading through this thread on different methods people organize the config. | 07:33:13 |

| Miles Dyson | For now, I just want the simplest way of doing things. | 07:33:59 |

I have a Sonic-pi loop running, and it clicks from time to time, same when I play any other media with audio. This kind of problem is not usually easy to troubleshoot over matrix. There really are a lot of different things that could be causing it, but it's probably not your NixOS config. It's more likely to be an issue with the audio routing in JACK. | 07:34:23 |
| @fractivore:cyberia.club | WAIT, actually though, it could be caused by using JACK without a Realtime kernel. | 07:34:44 |
| Miles Dyson | I do have security.rtkit.enable = true;. | 07:35:26 |
| @fractivore:cyberia.club | But really the possibilities are just too numerous... You'll have to do some troubleshooting on your end. Check your audio routing for rogue input from microphones and that sort of thing. | 07:35:29 |
| @fractivore:cyberia.club | With JACK it's really easy to get signal going to the wrong places. | 07:35:58 |
| Miles Dyson | Does jack and or pipewire require realtime? | 07:36:10 |
| @fractivore:cyberia.club | With sonic-pi it's easy to code up something that has artifacts. | 07:36:18 |
| Miles Dyson | The clicks happen when youtube videos play as well. | 07:36:50 |

Does jack and or pipewire require realtime? No, but anytime I try to do audio stuff using my usual stack without the realtime kernel, the audio sounds like trash in some way shape or form. It seems like the system can't keep up. | 07:37:47 |
| Miles Dyson | What is the process for installing and selecting a realtime kernel? | 07:39:08 |

The clicks happen when youtube videos play as well. IDK, could you have set the sample rate to something extreme? Can you check your CPU load using e.g. htop and see if it's related? I get clicks sometimes when I'm getting a lot of xruns, but just youtube shouldn't cause that. | 07:39:40 |
| @fractivore:cyberia.club | What's your hardware? | 07:39:50 |

I do have security.rtkit.enable = true;. I think this is all you need to do to enable the realtime kernel. | 07:40:05 |

I think this is all you need to do to enable the realtime kernel. Wait, maybe not, this just gives realtime scheduling priority to various processes.... | 07:42:33 |

| Miles Dyson | Damn . . . audio still scratches. | 08:10:00 |
 ckie (they/them; limited keyboard usage, voice preferred) | that memory clock looks awfully low for a modern Zen | 12:34:26 |
| ckie (they/them; limited keyboard usage, voice preferred) | oh I guess it's cpu clock and it's sleeping | 12:37:43 |
|  @bandithedoge:matrix.org joined the room. | 15:42:52 |
| Miles Dyson | The audio was clicking because of a codec. | 17:10:29 |

| Miles Dyson | the SBC-XQ codec causes audio problems. | 17:27:09 |
| Miles Dyson | It is a JBL bluetooth speaker. | 17:27:40 |
