Il m'est impossible de passer ma dongle bluetooth (Sony Erricson MW600) en A2DP. Du coup j'ai une qualité de son horrible.
Ce problème est venu à la suite de mise à niveau de gnome-shell 3.16, c'est surement durent cette mise à niveau que pulseaudio et bluez ont dut ce mettre à jour.
Je pense surtout que c'est pulseaudio le passage à la version 6.0.
Bon je ne sais pas vraiment quoi mettre comme information donc je mettre celles que j'ai trouvées avec des erreurs.
Avec l'interface graphique de Gnome je vois bien le périphérique avec la possibilité de le passer en A2DP mais il ne veut pas le passer.
Parfois la dongle est bien connectée mais elle n’apparaît plus dans les paramètres de son.

Mais ça ne règle pas le problème.
Après j'ai essayé avec pacmd list-sinks :
