I was sitting here wondering if it's possible to write a greasemonkey script that would detect sites like payperclick and mute the audio so the ad isn't heard.
I realize that I could accomplish the same thing in a better fashion by simply removing the ad text through a greasemonkey script but for purposes of curiousity, I wondered if you can disable the audio through javascript.
The only way I can see this being possible is if:
1)the ad has its own "mute button" which called a javascript function...in which case you could just call that function yourself.
2) The plugin the ad is using for audio has a javascript API (same as 1)
3) IE only: some bizarre IE ActiveX thing that could probably do it...by accessing stuff that it probably shouldn't.
All of these I consider extremely doubtful
Any other possibility would be too low level for javascript to have access to (or at least I seriously hope that is the case). A browser by itself has no volume controls....all multimedia are done by plugins.
