Steps to reproduce:

In my computer, I have two audio cards, A and B (can be one onboard, another add-on card)
I go into control panel/sounds/audio and switch Default Device from A to B 
I return to firefox, go to youtube, and playback something that has sound




Actual results:

It plays back on A. 

I close and reopen Firefox, then it plays on B.


Expected results:

It should play on B at once.

Does it work in other browsers like Safari, chrome or Opera ?
The video and audio on youtube is done by the Flash plugin and not Firefox unless you switched to the Youtube html5 beta test.

I don't have any of these; but I just tried it in IE8, with Flash, and it worked as I expected. I.e. IE8 played video with the sound coming from A, then I switched audio input from A to B, then when I started playing another video in IE8 (without closing/reopening IE), the sound went to B. With Firefox, need to close/reopen it for the same result.

1. I did not switch neither in Flash, nor in HTML5, which I also tried.

2. As noted above, I verified that IE8 is able to switch audio output even in Flash. So this is probably possible for Firefox as well, if only Firefox takes the effort to do it, which it looks like it does not.

type: I did not switch -> It did not switch

comparing with IE is bad if it comes to plugin because they use a different plugin (ActiveX).

>1. It did not switch neither in Flash, nor in HTML5, which I also tried.
That is good to know. Flash is another layer of something that we can not control but html5 is our code.
