Webplugin: Can't get/set volume/mute if playback was stopped
If you stop the playback, vlc.audio.mute returns always false and vlc.audio.volume always -1. And setting values will be ignored. But it seems that the correct values are still saved in the background, because if you start the playback again, you can get the last set values. (For example if audio was muted before stopping, it will be muted again)
This behavior is really bad if you want to change the volume/mute state if nothing is playing.
Since v2.2, this problem appears NOT after loading the plugin.
It seems that this is a LibVLC problem.
