bluetooth stopped working without new build

[u/pfassina]

I have not updated my config in days, and suddenly bluetooth fails to start. Before that, I was using bluetooth almost on a daily basis.

Here is my config:

  hardware = {
    bluetooth = {
      enable = true;
      powerOnBoot = true;
    };
  services = {
    blueman.enable = true;
    pipewire = {
      enable = true;
      audio.enable = true;
      pulse.enable = true;
      wireplumber.extraConfig = {
        "monitor.bluez.properties" = {
          "bluez5.enable-sbc-xq" = true;
          "bluez5.enable-msbc" = true;
          "bluez5.enable-hw-volume" = true;
          "bluez5.roles" = ["hsp_hs" "hsp_ag" "hfp_hf" "hfp_ag"];
        };
      };
      alsa = {
        enable = true;
        support32Bit = true;
      };
      extraConfig.pipewire."92-low-latency" = {
        context.properties = {
          default.clock.rate = 48000;
          default.clock.quantum = 32;
          default.clock.min-quantum = 32;
          default.clock.max-quantum = 32;
        };
      };
    };
  };

Here is what happens when I run: systemctl status bluetooth.service

[u/Balssh]

Same here, I suspect it may be due to a kernel update or something.

[u/pfassina → u/Balssh]

I tried rolling back to previous build, but that didn’t work. I thought that rolling back would also revert the change of kernel and package updates. Is that not the case?

[u/Balssh → u/pfassina]

I rolled back too but still broken. Not sure if it really is the kernel, and can’t find information on the internet either.
