So, unless I find THE ideal solution, you have no choice but to use Bluetooth USB dongle. Long story short: The real problem comes from built-in WiFi-Bluetooth chipset: BCM43438 (and/or its driver/firmware)īecause I used external Bluetooth transceiver (USB dongle), and now my headset works perfectly (AD2P & HSP) So here you will save your time and focus on the major root cause. With all that effort, I start to have clear idea of the problem. I keep my previous post for history (not anymore updated): After so many weekends spent to find a solution, I ended up with a lot of information and no workaround, a sort of puzzle parts that I’m still collecting over all Google results, I’m not exaggerating if I tell you that I already read every single page that Google can propose for this topic. What appeared to be a configuration issue turned to a real headache.

If you are here, it means that you are trying to use your headset’s microphone AND speakers with Raspberry Pi 3. I’ll write soon a post to explain that, but as far as I see, this is not resolving the main problem that is Bluetooth microphone input, this needs to be solved in the BCM chip firmware, to be continued… Update : For people who asked me if the new Raspbian Stretch changes anything here, yes, the new Raspbian brings PulseAudio v10 but not installed (by default, that’s not all), Raspberry Pi Foundation chose to go back to ALSA and use Bluez-alsa module.
