Bluetooth headsets - what works?
#1
Lightbulb 
I tried to get my sennheiser hd 4.50 to pair using the included OS. It sees the headset, but fails during connect.

Has anyone had luck connecting BT headphones? 

If so, what works? Did you do anything special to get it to pair?

Also, after disabling BT from the panel app, it cannot be re-enabled without rebooting.

I had initial success with a pair of J-Lab Flex headphones, with audio playback. But after one suspend cycle, I can not pair, re-pair, or connect any BT profile via the GUI (A2DP, HFP)

The error message "Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available" is displayed. I have not attempted CLI yet.
I had yet to make further progress on this project. I am up to date via script and manual apt-get update/upgrade.

BT pairing worked fine with the Ubuntu Mate image. Hopefully it can be fixed in the stock Debian.

Pairing also works with Manjaro. Selecting the A2DP profil requires a few steps (once paired, hit the play button on my headset and then manually select the A2DP profile), but audio stutters when wifi is connected (even with local audio). Clues anyone?

Note: for pairing to succeed, pulseaudio-bluetooth must be installed first.

I was able to pair some generic BT headphones I got off Amazon with Manjaro very easily. No extra steps required after pairing.

No problems pairing a Logitech speaker can (over A2DP) with my PBPro running Manjaro.

If you have troubles pairing, past experience (Sailfish OS on Sony Xperia phones) says that you could have more chance over the command line interface.

Didn't have that problem on my PBPro, but on my Dell Lattitude work laptop, I need some time to restart bluetooth between my initial pairing setup and subsequent uses (connections) If I didn't restart it before the first use connection would similarly fail. Once restarted, each subsequent connection worked perfectly.

Hope that helps.

You could be missing the package pulseaudio-module-bluetooth . It isn't included by all distros. I know at least the first couple Manjaro releases lacked it.

Install that package and reload pulse audio (or maybe just restart?)

Try the performance cpu governor. It's set to ondemand i think by default and it may not be aggressive enough to deal with things like youtube.

Thanks for the suggestion. Tried it, no changes. This likely is a software/tuning issue since my headset works flawlessly with the same hardware running the Android 7.1 image. Nevermind youtube, simply testing the headset from the audio panel also stutters.
