Yep, Media API is supposed to handle this, that why I asked them to be
though in an integrated manner maybe being registered in the same
interface (although hfp is not really media only), anyway basically we
should have pa acting as a2dp source/sink and/or hfp gateway/headset
endpoint handling the audio. So in essence ofono is acting as a
controller/target in a very similar way as avrcp does for a2dp,
although for avrcp we don't really need an agent as we use uinput.
