Hi, new to ZenPhoto and I really want to use this feature in my kid's site. I started uploading flv's and notice that the sound is off by default when user clicks on thumbnail to view the video, until you click on the volume slider. Where do I go to make the sound on by default?

The answer will depend on which player you are using. The generic answer it that the player plugin sets up the options for the player. You would have to look at the player documentation to find the thing to set and add that to the setup code in the player plugin.

Actually none of our three video players should have sound disabled by default.
