[Solved] Bluetooth SBC profile no longer available

Help
1

Hello,

The following config used to enable SBC profile for my ‘Bose QC35 II’ headset. However, it no longer does it after system updates. Is there any way to bring it back?

   hardware.bluetooth.enable = true; # enables support for Bluetooth     
  hardware.bluetooth.powerOnBoot = true; # powers up the default Bluetooth controller on boot    
  services.blueman.enable = true;    
  hardware.bluetooth.settings = {    
    General = {    
      Enable = "Source,Sink,Media,Socket";    
    };    
  };     
  services.pipewire.wireplumber.extraConfig.bluetoothEnhancements = {    
  "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" ];    
  };    
};

I see the following message when i turn on the headset,

lappy bluetoothd[1518]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for 2C:41:B2:21:C1:12: Protocol not available

I removed services.pipewire.wireplumber.extraConfig.bluetoothEnhancements and hardware.bluetooth.settings.General blocks and SBC codec showed up.
