Can't connect bluetooth headphones

[tugunchinov]

I have Honor Earbuds 2 Lite, which I can't connect to my laptop. Sometimes I can't see it, sometimes I see, but can't pair. What can I do?

I've already tried pulseaudio -k, and something else.

Any help, please.

lspci doesn't give the information about your system that is needed. You should post results of

Code: Select all

inxi -Fxxxrz

or results of the program "system info" and copy/paste the system information results. Unfortunately, USB to headphones in LM isn't as simple as it should be. You didn't mention your operating system details so I'll assume its LM 20.2 cinnamon. If so you may need to manually connect your headphones using your bluetooth bluemon applet and then go to your sound settings and see if you can select it in the output. Once connected, you may need to manually disconnect and remove from the bluetooth list to reconnect again next time. At least I have to.
