I've got a Lenovo Thinkpad T460 and a fresh installation of Fedora 27 with only a few Gnome Extensions and extra software installed. I got this laptop a few months now and only used Fedora (previously 26) with it. This problem existed the whole time (also similar bluetooth problems with my previous laptop [Lenovo Ideapad U410], with Ubuntu Gnome and also Fedora) and I thought I should try to reinstall the OS first and check if this was the problem.

I got a logitech bluetooth audio connector (this one) which is connected to my sound system. When I installed Fedora 27 I connected to this device and successfully listened to Spotify with this device. But after about half an hour it didn't work any more. Since then I tried it several times and got into one of the following situations:

  • The os completely froze! When trying to connect to the device or turn on/off bluetooth. Only hard rebooting the notebook helped me then
  • Connecting to the device works and I can listen a few minutes. Then suddenly playback stops and the device is still connected and recognized, but I can only listen to music/get sound through the notebook speakers
  • Connecting to the device doesn't work at all
  • Connecting to the device works, but it isn't recognized as a sound output device

So here I am with this nice laptop with built in bluetooth and it doesn't work which is not good. I have to admit that although I'm experienced with Linux and computers I don't know how to troubleshoot, find the problem or even fix this. I googled around and found this tutorial to manually pair bluetooth devices under Fedora over the CLI which I tried. Result:

[bluetooth]# devices
Device C8:84:47:08:5A:47 (47)Logitech Adapter
[bluetooth]# connect C8:84:47:08:5A:47 
Attempting to connect to C8:84:47:08:5A:47
Failed to connect: org.bluez.Error.Failed

As you can see the error message isn't helpful at all. So can anyone help me? What can I do to troubleshoot this? Where do I start? What can I check? (And yes, the Logitech device is working fine with my Android phone).

  • I find that running # disconnect C8:84:47:08:5A:47, after that org.bluez.Error.Failed error message usually fixes things. If that doesn't help, try disconnecting, exiting bluetoothctl and running "pulseaudio -k". – Steeve McCauley May 4 '18 at 12:38

I solve this problem with de comand line: pulseaudio -k

  • Pulseaudio usually fixes things if there's an audio driver crash, while possible, nothing in the OPs post suggests this is the case. – ffledgling Jan 5 '18 at 11:39
  • Usually disconnecting with bluetoothctl fixes the problem, but I have had some success on more than one occasion with resetting pulseaudio as suggested by Fagner Sutel. – Steeve McCauley May 4 '18 at 12:31
