--- Comment #1 from Ada Chan <adachan at apple.com> ---
We are proposing a new plugin API to accomplish this:

When the browser wants to mute or unmute a plug-in it will call NPP_SetValue with the

NPNVmuteAudioBool = 4000

NPNVariable. The value parameter should be a pointer to an NPBool. The plug-in can query the browser for the value using NPN_GetValue.

Note that the value of “NPNVmuteAudioBool” does not affect the plug-in’s audio playing state. “NPPVpluginIsPlayingAudio” and "NPNVmuteAudioBool” can both be true at the same time. The plug-in may still be playing audio, but the user won’t be able to hear it if the plug-in is muted.
