[SOLVED] bluetooth and hci0 interface

I am trying to connect to a bluetooth speaker with the bluez pacakage. I can do it all right with "bluetoothctl -- connect <Device>". But when I reboot my  system and run it, then it fails (at first); after reboot, if I start firefox and run the same command, the device connects. So I reboot my system and started the bluetoothctl console and tried to connect with the device and it fails  (I haven't started firefox yet).

[bluetooth]# connect F8:5C:7D:AC:31:F9
Attempting to connect to F8:5C:7D:AC:31:F9
[bluetooth]# Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable

Now if I start firefox the console shows me this ( I did not do anything except start firefox):

[bluetooth]# connect F8:5C:7D:AC:31:F9
Attempting to connect to F8:5C:7D:AC:31:F9
[bluetooth]# Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable

I tried changing the device Class to 0x006c010c in /etc/bluetooth/main.conf. But it produced no results. It's not a problem for me that I have to start firefox. I will start it anyway. I want to understand what's going on here and if  there's a possible solution?

Re: [SOLVED] bluetooth and hci0 interface

It's more likely that the sound daemon is socket activated rather than enabled, are you using pulseaudio or pipewire?

systemctl --user status pipewire{,-pulse}.{service,socket} wireplumber.{service,socket}

I am using pulse. Enabling the pulseaudio daemon for the current user solved this problem. Thanks a lot.
