I am experiencing the same problem, however, switching to HSP/HPF and back will not work (when selecting A2DP from the dropdown menu in the audio settings, the output sink switches to internal audio and when reselecting bluetooth it is again in HSP/HPF mode). Only connecting as HSP/HPF and then switching to A2DP will allow for HiFi sound.
A more convenient workaround can be found here: https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae Running a2dp.py after connecting fixes the problem. The page also provides an automated solution using a dbus-loop below. Or you can find an implementation using udev rules here: https://askubuntu.com/questions/910501/udev-rule-to-run-python- script/912838#912838 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1582213 Title: [xenial] Bluetooth device doesn't play any sound in A2DP mode unless set to HSP/HFP first Status in bluez package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Bluetooth device doesn't play any sound in A2DP mode unless set to HSP/HFP first --- I have a Sennheiser MM 450-X headset. In 15.10, connection & playback was straightforward. In 16.04, the headset connects, and shows up as default playback device on `pavucontrol`, but there is no sound. A functional workaround is to, after having connected it, to go the `Configuration` tab, and in the `Profile` dropdown, to choose `... HSP/HFP`, which will make them play as expected (but in low quality), then switch to `... A2DP Sink` (they will play in high quality).
