I don't have a deep knowledge of how the sink latency should be
calculated and reported. My understanding of this is that
FIXED_LATENCY_PLAYBACK_A2DP is synthesizing the over-the-air A2DP
latency (which can be calculated with the current specification of
AVDTP), and then we set a fixed latency for the sink in
a2dp_set_bitpool adding up this FIXED_LATENCY_PLAYBACK_A2DP and the
time the whole data buffer takes. If my assumptions are right, then I
think we should keep using thread_info.fixed_latency in
PA_SINK_MESSAGE_GET_LATENCY. What are your thoughts about it?
