Bug Description

I'm running Ubuntu 16.04.1 LTS, preinstalled on Lenovo G50-70.

Blueman version is 2.0.4-1ubuntu2.

I expected my Sony MDR-ZX770BT stereo headphones to play through Bluetooth in stereo. Instead, I get mono sound through both sides of the headphones.

When I try to switch the audio mode to A2DP in Blueman, I get this error message: Failed to change profile to a2dp_sink.

I have Bluetooth rtl8723be in my computer, and have been told on ubuntu forums that this is probably the cause of my bug.

I couldn't find Blueman in the list of debugging procedures.

Thank you for you help.
Kind regards,
Kathleen
