+Audio support
+'''''''''''''
+
+Since version 1.8.5, Futatabi has limited audio support. It is recorded
+(assuming Nageru is also at version 1.8.5 or newer) and saved for all inputs,
+and played back when showing a replay, but only when the replay speed is at
+100%, or very close to it. (At other speeds, you will get silence.)
+Furthermore, there is no local audio output; the Futatabi operator will not
+hear any audio, unless they use a video player into the Futatabi stream locally
+(with associated delay). All of this may change in the future.
