I'm using Ubuntu 16.10, bluez "5.41-0ubuntu3", and pulseaudio "1:9.0-2ubuntu2.1". From <a href="https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1438510">https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1438510</a> <a href="https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1577197">https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1577197</a> it looks like the sequence that works is: 1. Select the "off" profile in pulseaudio. 2.1 Disconnect the bluetooth earphones. 2.2 Reconnect the bluetooth earphones. 3. Select the "a2dp_sink" profile in pulseaudio. Or for commands: 1. pactl set-card-profile bluez_card.00_18_09_62_4B_98 off 2. bluetoothctl 2.1 disconnect 00:18:09:62:4B:98 2.2 connect 00:18:09:62:4B:98 3. pactl set-card-profile bluez_card.00_18_09_62_4B_98 a2dp_sink Bluetooth users are resorting to a scripted version of the above as a workaround: <a href="https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae#file-a2dp-py">https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae#file-a2dp-py</a> What I'm seeing in /var/log/syslog if I select "a2dp_sink" as the profile, then disconnect, and reconnect: Nov 25 00:47:50 fireflower pulseaudio[2178]: [pulseaudio] module-bluez5-device.c: Default profile not connected, selecting off profile Nov 25 00:47:50 fireflower bluetoothd[970]: /org/bluez/hci0/dev_00_18_09_62_4B_98/fd17: fd(24) ready Nov 25 00:47:50 fireflower pulseaudio[2178]: [pulseaudio] bluez5-util.c: Transport TryAcquire() failed for transport /org/bluez/hci0/dev_00_18_09_62_4B_98/fd17 (Operation Not Authorized) Nov 25 00:47:50 fireflower kernel: [ 7852.918655] input: 00:18:09:62:4B:98 as /devices/virtual/input/input37 The message from bluetoothd "fd(24) ready" showing up then makes me wonder if this is a race between pulseaudio and the bluetooth connection? If I then run: pactl set-card-profile bluez_card.00_18_09_62_4B_98 a2dp_sink I get nothing new in /var/log/syslog . If I run: pactl set-card-profile bluez_card.00_18_09_62_4B_98 off I get nothing new in /var/log/syslog . If I again run: pactl set-card-profile bluez_card.00_18_09_62_4B_98 a2dp_sink I get this output: Failure: Input/Output error and /var/log/syslog logs: Nov 25 00:52:26 fireflower pulseaudio[2178]: [pulseaudio] bluez5-util.c: Transport Acquire() failed for transport /org/bluez/hci0/dev_00_18_09_62_4B_98/fd17 (Operation Not Authorized) If I run pactl list cards | tail -n 26 I see: Card #18 Name: bluez_card.00_18_09_62_4B_98 Driver: module-bluez5-device.c Owner Module: 43 Properties: device.description = "MDR-ZX220BT" device.string = "00:18:09:62:4B:98" device.api = "bluez" device.class = "sound" device.bus = "bluetooth" device.form_factor = "headset" bluez.path = "/org/bluez/hci0/dev_00_18_09_62_4B_98" bluez.class = "0x240404" bluez.alias = "MDR-ZX220BT" device.icon_name = "audio-headset-bluetooth" device.intended_roles = "phone" Profiles: headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 20, available: yes) a2dp_sink: High Fidelity Playback (A2DP Sink) (sinks: 1, sources: 0, priority: 10, available: yes) off: Off (sinks: 0, sources: 0, priority: 0, available: yes) Active Profile: off Ports: headset-output: Headset (priority: 0, latency offset: 0 usec, available) Part of profile(s): headset_head_unit, a2dp_sink headset-input: Headset (priority: 0, latency offset: 0 usec) Part of profile(s): headset_head_unit If I disconnect and connect the device via bluetoothctl, /var/log/syslog logs: Nov 25 00:55:38 fireflower acpid: input device has been disconnected, fd 15 and Nov 25 00:57:02 fireflower kernel: [ 8404.425497] input: 00:18:09:62:4B:98 as /devices/virtual/input/input38 If in the "Sound" GUI (System Settings > Sound), I go to the Output tab, and select the headset, /var/log/syslog logs: Nov 25 00:57:37 fireflower pulseaudio[2178]: [pulseaudio] backend-native.c: connect(): Function not implemented If in the pulseaudio "Volume Control" UI I go to the Configuration tab, it shows the profile is "Off".
