Bonjour,
J'ai un casque Bluetooth JBL 720BT que j'ai réussi à connecter en Bluetooth en ayant installé le gestionnaire Bluetooth Blueman mais le son audio qui en sort est uniquement en mono. J'ai aussi installé bluez, ça n'a rien changé. Ai-je quelque chose à configurer ou installer sur pulseaudio pour du son stéréo ? J'ai cru comprendre que c'était un problème non résolu récent sur pulseaudio en parcourant les forums Ubuntu, qu'en est-il ?
Voici ma carte son : Intel High Definition Audio.
Infos dans alsamixer : Carte : HDA Intel PCH avec Puce : Realtek ALC256.
Driver : snd_hda_intel.
J'utilise Zorin OS Core 17.2 et j'ai installé tous les packages *blueman* et *bluez*.
Merci pour votre aide !

Hello,
I have a JBL 720BT bluetooth headset that I managed to connect via bluetooth by installing the blueman bluetooth manager but the audio coming out is only mono. I also installed bluez, but it didn't make any difference. Is there anything I need to configure or install on pulseaudio for stereo sound? I understand that this is a recent unresolved problem on pulseaudio, what about it?
Here's my sound card: Intel High Definition Audio.
Info in alsamixer: Card: HDA Intel PCH with Chip: Realtek ALC256.
Driver: snd_hda_intel.
I'm using Zorin OS Core 17.2 and have installed all blueman and bluez packages.
Thanks for your help!

Welcome to the Forum!
When You go in PulseAudio to the Configuration Tab, you should get for Your Speakers a Dropdown Menu like this:
Look if You can choose there Your Sound Profile.

Bienvenue sur le Forum !
Lorsque vous allez dans PulseAudio à l'onglet Configuration, vous devriez obtenir pour vos haut-parleurs un menu déroulant comme celui-ci :

Regarde si tu peux choisir ton profil sonore.
Hello,
Yes, I saw it, but there is not something for my JBL... And I'm not looking for a solution for external speakers but for headphones. But thanks for your answer 
Yes, I understand that. The Picture was only an Example. Your Headphones should be listed there, too. Are they listed? And if yes: what Options are shown to You?
Here is what I have. I don't understand why A2DP reading is unavailable. I have sound, but it is in a bad quality. Do I have to install something ?
I also have that :
Is Mono sound a normal thing with headphones ?
No.
You could look for Codecs. When You go to Gnome Software, scroll down to the End and there click on the ''Codecs'' Button, You come to an Overviwe where Codecs are listed. Install them all, make a Reboot and look if it works.
If that shouldn't be enough, you could install the ubuntu-restricted-extras Package. That includes some more Codecs (and Microsoft Fonts). To install it, type in the Terminal sudo apt install ubuntu-restricted-extras but to say that: during the Installation will come a Window for Licence Agreement; that is because of the Microsoft Fonts in this Package. With the Tab Key You can navigate.
Onther Point could be this on Your Picture:
Because there is a Dropdown Menu, look what Options do you have there and check if another one maybe works. Especially after installing the other Codecs.
After installing all codecs and ubuntu-restricted-extra, without effects, I finally solved my problem in the following way, following the discussion available here: https://forums.linuxmint.com/viewtopic.php?t=349487
I entered : sudo dpkg-reconfigure bluez then sudo dpkg-reconfigure linux-sound-base: there, a window opened asking me to choose the sound profile between ALSA and OSS. I chose ALSA.
I reactivated Bluetooth. The headset connected well and it automatically connected to “High Fidelity Playback (A2DP)” and new codecs are available in the Pulse Audio Configuration tab. I left the one indicated, preferring not to touch anything now that it's working. Here's what I've now :

Good to see that it works now.

A little update : I had to do again the solution I found after an installation of Zorin OS updates (via update manager). Don't know why. But it is solved.
