Public bug reported: I'm not really sure this problem is with bluez, pulseaudio or firefox. The main symptom is that Firefox refuses to send audio to my AD2P compliant bluetooth speakers. I can select the speakers with the gnome- control-center for bluetooth and play the test sounds (even while FF is playing sound through the computer (DELL N7010 laptop) speakers. Even VLC has the same problem so I suspect this is a system problem and not an application problem.
Note - I installed pavucontrol and was able to switch the audio of a playing youtube to the bluetooth speakers. now for your recommended info lsb_release says Ubuntu 17.10 Firefox is Version 59.0.1 dpkg -l | grep -i blue says ii bluez 5.46-0ubuntu3 amd64 Bluetooth tools and daemons ii bluez-cups 5.46-0ubuntu3 amd64 Bluetooth printer driver for CUPS ii bluez-obexd 5.46-0ubuntu3 amd64 bluez obex daemon ii bluez-tools 0.2.0~20140808-5build1 amd64 Set of tools to manage Bluetooth devices for linux ii gir1.2-gnomebluetooth-1.0:amd64 3.26.1-1 amd64 Introspection data for GnomeBluetooth ii gnome-bluetooth 3.26.1-1 amd64 GNOME Bluetooth tools ii libbluetooth3:amd64 5.46-0ubuntu3 amd64 Library to use the BlueZ Linux Bluetooth stack ii libgnome-bluetooth13:amd64 3.26.1-1 amd64 GNOME Bluetooth tools - support library ii pulseaudio-module-bluetooth 1:10.0-2ubuntu3.1 amd64 Bluetooth module for PulseAudio sound server ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: bluez 5.46-0ubuntu3 ProcVersionSignature: Ubuntu 4.13.0-37.42-generic 4.13.13 Uname: Linux 4.13.0-37-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sat Mar 24 14:10:02 2018 EcryptfsInUse: Yes InstallationDate: Installed on 2018-03-19 (5 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20180105.1) InterestingModules: rfcomm bnep btusb bluetooth MachineType: Dell Inc.
