When I switch to headset_head_unit profile, I can no longer send audio to the headset. I first went to pulseaudio to see if they had any suggestions as I found a very similar case to mine (https://bugs.freedesktop.org/show_bug.cgi?id=97064). > > Tanu kindly pointed out that there seemed to be missing a dbus signal from bluetoothd, specifically "PropertiesChanged" signal on MediaTransport1 interface. I did some inspection, and transport_update_playing() in profiles/audio/transport.c shows Playing = 0 and not 1, which is the case when using a2dp_sink profile. > > Headset_head_unit: > bluetoothd[756]: profiles/audio/transport.c:transport_update_playing() /org/bluez/hci0/dev_00_11_C2_08_15_F6/fd0 State=TRANSPORT_STATE_IDLE Playing=0 > > a2dp_sink: > bluetoothd[756]: profiles/audio/transport.c:transport_update_playing() /org/bluez/hci0/dev_00_11_C2_08_15_F6/fd0 State=TRANSPORT_STATE_ACTIVE Playing=1 > > Any recommendation on what might be the issue? Happy to provide any logs that could be useful. Ever since we move HFP to be an external profile it no longer uses the transport API, instead you either use the native PA backend or oFono which has a dedicated interface for HFP, perhaps your controller is not set for HCI routing? -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
