I had to ask PulseAudio to use the A2DP sink only once, through the UI (either the Audio applet of Plasma, or pavucontrol, I don't remember). It's one too many, but since PulseAudio 12, A2DP should be the default [1]. As for using the microphone, I haven't tried but using the mic requires using the HSP profile unfortunately (because of the bluetooth specification). Other systems auto switch between the two profile. I think it is possible on Linux [2], but I hope it will come out of the box soon.
