The current editor will strip the sound trigger (if there is any).
Everything else is fine. The editor will be able to add/remove sound
triggers in the next release of JavE.

Ok, you are right. I am not very strong at documentation.

You have to look at the jmov specification at
  http://www.jave.de/player/jmov_specification.html
to find out all about the new applet parameters SOUND and SOUNDSTART and
about the new sound trigger event # in the jmov file.
You can download the player form:
  http://www.jave.de/player/javeplayer12.zip
And its source code:
  http://www.jave.de/player/javeplayer12src.zip

Well, here is all (I think) you have to know about sound support:

 * The sound file must be in *.au format, recorded at 8 KHz, mono, in
mu-law encoding. If your audio clip is in a different format (e.g.,
.wav) or a different frequency it must be converted to the exact
specifications above before Java can play it. To convert files from
different formats search your favorite for GoldWave for Windows, sox for
Unix and similar conversion utilities for other systems.
 * To add the sound file to the applet add an applet parameter, for
example:
    <PARAM NAME="SOUND" VALUE="waltz.au">
 * To specify the way to play the audio file specify another applet
parameter:
    <PARAM NAME="SOUNDSTART" VALUE="EVENT">
   Valid values are:
    "EVENT": To start the sound file event driven (at a certain frame -
one or more)
    "ONCE": To start the sound file right when starting the animation
    "LOOP": The same as ONCE, but the sound file will be played looping
endlessly.
 * For the event-driven sound playback you have to manually (at the
moment) add a line containing only # in the jmov file right after the
frame(s) where you want to play the sound file at. Example:

J:A61 8 %0%10 /\%0%7 __/  \._%21 .%3-.%0%7 \
J:A61 8 %0%10 /\%22 .%3 .%0%7 __/  \._%20 .- .
#
J:A61 8 %0%10 /\%0%7 __/  \._%0%7 \  ,-,-.\

Playing the sound file will start when showing the second frame.
