Hi, I'm currently using a recent Raspbian release (kernel 4.1.18) with BlueZ 5.38 and Pulseaudio 8.0. I would like to enable the HSP profile to send audio from my raspberry to my headphones. I can discover and pair the device and even get music with A2DP. However, when I switch to HSP (using pavucontrol), I get the following error : "backend-native.c: connect(): Function not implemented". With pactl list cards, I get the following regarding Bluetooth : Profiles: headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 20, available: yes) a2dp_sink: High Fidelity Playback (A2DP Sink) (sinks: 1, sources: 0, priority: 10, available: yes) off: Off (sinks: 0, sources: 0, priority: 0, available: yes) So it seems that HSP profile is available. I tried to revert to pulseaudio 7.1 and 6, but the result is the same. Any idea of what could cause this issue ? Thanks !
