I have a Klipsch KMC 3 bluetooth speaker that I’d like to use as the primary audio device on my openSUSE Tumbleweed system, but I can’t seem to get it to work. I’m able to connect to it just fine using the Bluetooth applet. Both the PC and the speaker show an active bluetooth connection. However, when I go to sound settings, the Output tab has an empty devices field. There’s no device to select for sound. If I plug in my headphones using the 3.5mm audio jack, those show up in the hardware tab as “Headphones - Built-in Audio” and work normally. For whatever reason, this bluetooth speaker, while successfully paired with the PC, won’t show up as an audio device. What can I do to make it visible to the sound system?
Does your bluetooth adapter support the profile wanted by your bluetooth speaker?
Are there any error messages related to bluetooth?
The result of
dmesg | grep uetooth
and some more information about your system (DE, details on your bluetooth adapter, …) might help to analyze your problem in more detail.
Best regards

I’m running Gnome 3.20.0 on openSUSE Tumbleweed (20160408) (x86_64) 64-bit on an Intel NUC (NUC5i7RYH). Checking Intel’s specs for this device, they label the radio as “Bluetooth 4.” Here’s a readout on the Bluetooth hardware:

I don’t know anything about the speaker profile or what the adapter supports. Let me know if I can provide anymore information.
Your bluetooth stack seems to be up and running without any errors.
I’m not familiar with GNOME so i don’t know which GUI-tools it provides for bluetooth handling (and i’m not a bluetooth expert either ;)).
Occasionally i have used some command line tools to play around with bluetooth:
sdptool -i hci0 browse
should show you which bluetooth services can be handled by your bluetooth adapter. Probably “hciconfig” and “rfcomm” can help you as well to investigate/handle your devices. Please consult the man pages for what and how you can use them.
Sorry, nor do i. But the documentation provided with the speaker, the manufacturers internet page or your preferred search engine may be a good place to start your serach.

check in gnome blutooth management tool that your bluetooth speakers set is:
- paired
-trusty
-connected
if it is thus it seems an upper layer problem.
gnome uses pulseaudio
install pavucontrol
launch pavucontrol then go to “settings” tab"
does you speakers set appear in the list?
is the profile “…A2DP…” ?
I’m not sure what you mean by Gnome Bluetooth Management Tool. If I click on the upper-right corner, a menu drops down with various items. One of those items is an indicator that the Bluetooth speaker is connected, and under that is an option that says “Bluetooth Settings.” I presume this what you mean, but that just brings up a window that shows connected/available devices and an option to turn bluetooth off. I can click the connected Klipsch speaker and see that it is paired and connected, but nothing about “trusty.” I’m not sure if this is relevant to the issue, but it recognizes the Klipsch KMC 3 as a headset (with microphone) rather than just a speaker. Maybe that doesn’t matter.
I have pavucontrol installed and can open it, but there is no “settings” tab. The available tabs are Playback, Recording, Output Devices, Input Devices, and Configuration. The speaker does not appear in any list on any tab.
gnome blutooth management tool
i don’t know gnome environment but only kde environment then i use a general term for the tool perhaps it is “gnome bluetooth applet”.
you must check if your bluetooth device is :
- paired
- trusted (thus your pc does not ask each time an authorization when connecting your device)
- non blocked
- connected
generally you find this info in the gnome bluetooth management tool.
if one of these conditions is not satisfied then your device does not appear in “configuration” tab in pavucontrol
you can try also this :
- keep bluetooth enabled and your device connected
- rename the folder ~/config/pulse/ to another name to save it
- restart your pc
this will re-init pulseaudio for your profile. pulseaudio will re-detect all sound cards and sound devices thus i hope pa will detect your bluetooth device.
A Bluetooth dongle is found when plugged in:

Each time I do this a melody is played by the speaker. But when playing a movie there is no sound from the Bluetooth speakers. Any idea?

Play something and see in pavucontrol.
Installed that and got a nice display showing 2 devices:
- Internes Audio Analog Stereo, Port Line Out (plugged in)
- atsA910, Headset
**Yast > Audio **only shows the first one. I am clueless how to cofigure the second one.
Pavulcontrol is application specific you set the output (or input) for each application so one app can be set to use one channel and another one a different channel,
Can’t connect anymore.
