-/** @file patest_sync.c
-    @ingroup test_src
-    @brief Test time stamping and synchronization of audio and video.
-
-    A high latency is used so we can hear the difference in time.
-    Random durations are used so we know we are hearing the right beep
-    and not the one before or after.
-
-    Sequence of events:
-        -# Foreground requests a beep.
-        -# Background randomly schedules a beep.
-        -# Foreground waits for the beep to be heard based on PaUtil_GetTime().
-        -# Foreground outputs video (printf) in sync with audio.
-        -# Repeat.
