I have Bluetooth headphones Sony WH-1000XM3 and Ubuntu 16.04. I have successfully Paired the device but cannot change profile to a2dp. No matter what I did it keeps failing with the message "Failed to change profile to a2dp_sink".

I have tried:

Nothing works. Please Help.

What kind of works for me is a sequence as follows:

  1. Remove the headphones from Bluetooth devices if previously paired
  2. Enable pairing mode on the headphones
  3. Open Bluetooth settings and click add
  4. You may see already a device named LE_WH-1000XM3 of an unknown type at this point - don't pair it!
  5. Optionally select Headphones, headsets and other audio devices from the Device type filter drop down
  6. Wait until WH-1000XM3 device with the type Headset appears
  7. Pair it
  8. Run Blueman (install if you haven't yet), at this point the paired headphones device name starts with LE_WH- again
  9. Right click on the device and select setup
  10. Choose Audio Sink and click Next
  11. Only at this point my headphones say to me Bluetooth connected, yay! The device name changes to WH- without the LE_ prefix (although you'd need to close and re-open Blueman to refresh the name listed, you'll see in the sound settings anyway)
  12. Go to sound settings and ensure selected playback audio device is the headphones (might be not) and that the mode High Fidelity Playback (A2DP Sink) is selected (should already be)

Shortly, when headphones are connected as LE_WH-1000XM3 they don't work. It's not possible to change audio profile neither in Blueman nor mode in the sound settings, actually here they are not listed at all even though they were connected as an audio device (the wait from the point 6). When connected as WH-1000XM3 all audio functions are available and work fine (as much as there is any 'fine' for Bluetooth audio on Linux). Still may require manual selection of the desired audio profile but that's just a minor annoyance comparing the the whole headphones setup issues.

The poorest part is that as soon as I disconnect headphones and connect them again, they remain LE_WH-1000XM3 no matter what I do. So I need to unpair and go through the whole process again (╯°□°)╯︵ ┻━┻

Extra info: LE stands for Low Energy Bluetooth standard. I guess Headphones advertise connection in two modes, regular and LE. It's possible to connect with both but only for one audio is supported on Ubuntu 16.04. I'd like to know how to enforce the regular or completely disable the LE mode as it seems to always fallback to it and the whole pairing has to be done again.

  • It worked like a charm, thanks! The only difference was that the device name didn't start with `LE_` in Blueman (step 8). I haven't tried the disconnect/connect part, but just by being able to pair without having to change configuration files is already relieving. – mrgiesel Jan 07 '20 at 16:45

I'm adding another answer as I'm not sure yet how deterministic this way is. Moreover it's a workaround which compromises connectivity with Low Energy transport devices.

On my machine at /etc/bluetooth/main.conf there is following property:

# Restricts all controllers to the specified transport. Default value
# is "dual", i.e. both BR/EDR and LE enabled (when supported by the HW).
# Possible values: "dual", "bredr", "le"
#ControllerMode = dual

To disable the Low Energy transport, I've uncommented it and set the value:

ControllerMode = bredr

Then I restarted bluetooth service (or reboot) and (ra)paired my Sony WH-1000XM3 again under system Bluetooth settings. It worked straight away without even using Blueman or any other neck breaking tricks from the other answer I gave. Obviously the problem of connection falling to the device named LE_WH-1000XM3 doesn't exist now as Bluetooth host on the laptop doesn't listen for any LE devices. I hope this solves it for good.

I was in the same situation. Eventually installing bluez-5.52 perfectly solved this problem. It is said that bugs in previous version of bluez caused this issue. You can simply download the source code and run

./configure
make
sudo make install
sudo systemctl daemon-reload
sudo service bluetooth restart

Enjoy!
