Hi, I was trying to setup HFP uing ofono. I have the following setup Rasperry Pi B+ ( ARM1176JZF-S) Bluez 5.32 Pulseaudio 6.0 ofono 1.16
Used the following steps http://padovan.org/blog/2010/02/handsfree-profile-into-bluez-and-ofono/ start pulseaudio, bluetoothd and ofonod Connect to phone using bluetoothctl ./enable-modem ./dial-number loopback I was able to pair my nexus 4 device and use the script ./dial-number which actually sets a call up. But the audio of the call doesn't route to the default sink. I see the following error in ofonod *Reject SCO: Agent not registered* Which could be the reason for the audio problem. Things that I have already tried. Patched http://cgit.freedesktop.org/~jprvita/pulseaudio/ file bluetooth-headsets-media-api. Recompiled the raspbian kernel with *CONFIG_BT_SCOCONFIG_BT_HCIUSB_SCO* enabled Added *Enable = Source,Sink,Headset,Gateway,Control,MediaDisable = Socket* to /etc/bluetooth/audio.conf. Things that could be wrong When I do a pactl list cards, i see the bluetooth card at #0 with two profiles. * Profiles: a2dp_source: High Fidelity Capture (A2DP Source) (sinks: 0, sources: 1, priority: 10, available: yes) headset_audio_gateway: Headset Audio Gateway (HSP/HFP) (sinks: 1, sources: 1, priority: 20, available: no) off: Off (sinks: 0, sources: 0, priority: 0, available: yes) Active Profile: a2dp_source* But when I try making the headset_audio_gateway the default profile. I get *$ sudo pactl set-card-profile 0 headset_audio_gatewayFailure: Input/Output error* Also read this in the pulseaudio notes http://www.freedesktop.org/wiki/Software/PulseAudio/Notes/6.0/ "When building PulseAudio, it's possible to choose between "native" and "ofono" BlueZ 5 headset backends." How do I specify that I wish to use the ofono headset backend? Is that the problem?
