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).
