set firefox sound to new default sound device - quirky behavior windows 8

已張貼

My 64bit Win8 machine will direct sound to the default speakers as output but when I try to toggle the sound to a different devices such as e.g. 'headphones' the sound goes out. I am using the notification icons area on my PC to switch the sound output device which works acceptably in other browsers.

The exception I've noticed at least once on a TED talk video was if the sound/movie clip was loaded from the URL directly instead of as embedded in a webpage, the sound device selector native to the OS works fine.

I think that you need to close and restart Firefox after making changes to the default sound device to make Firefox pick up the change. Otherwise it might not work properly, especially when a built-in (HTML5) media player is used and not a plugin.
