Wait a minute, this might not be a bug at all... A2DP is uni-directional so doesn't support simultaneous audio output and input. In theory A2DP can be used for output or input, depending on what your peripherals support... https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Advanced_Audio_Distribution_Profile_.28A2DP.29
Generally speaking though, there is no microphone when a headset is in A2DP mode: http://www.tomsguide.com/answers/id-3286122/headset-mic-work-audio.html The PulseAudio "fix" for the previous bug involves automatically switching to the lower quality HSP/HFP profile when the microphone is required. This is triggered automatically according to what features the application requests. However automatic switching is apparently only implemented for VoIP applications according to the release notes: https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/10.0/ So automatic switching relies on the application supporting PulseAudio's "property media.role=phone". If it doesn't yet then that's an application bug. But beware that once switching has occurred and the mic turns on, your audio output is likely to also be low quality (HSP/HFP profile). This is just a fact of life with Bluetooth standards. This bug is therefore invalid for pulseaudio, but your app(s) might be able to add the above feature to trigger the automatic switching. If you're having trouble with a specific app then please click on one of the "Also affects..." links at the top of the bug. ** Changed in: pulseaudio (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1711087 Title: ad2p sink profile mic not available Status in pulseaudio package in Ubuntu: Invalid Bug description: I have a bose soundsport bluetooth headset. When I select the ad2p sink profile there is no microphone available. Only with the HSP profile my microphone is available. It's really annoying to have to switch between profiles to make a call or to listen to normal quality music.
