sound: latency and synchronization measurements

[ Please keep me in CC as I'm not subscribed to the list] Hi All, I am trying to characterize the audio synchronization between two systems. There is a mechanism to route audio between two systems, we run ‘aplay’ at one system and ‘arecord’ in other system. We need to measure the time
