how can I mute flash volume using swfobject

Hi Experts,

I'm working on a site with a flash presentation embedded in the main banner.  It's set up to start rotating images and playing audio when page loads. (not my idea).

I reconfig'd it to use swfobject to get SEO control over the host div contents and everything works fine.  But I want to mute the audio on page load.  Is there a param that I can use?

Thanks,

HNM

                  params.wmode = "opaque";

                  var attributes = {};

                        

                  swfobject.embedSWF("http://www.xyz.com/flash/index1.swf", "topFlash", "986", "304", "9.0.0", false, flashvars, params, attributes);

                  

                  swfobject.embedSWF("http://www.xyz.com/flash/abc_flash.swf", "rightMidFlashPromo", "314", "138", "9.0.0", false, flashvars, params, attributes);
