select sound device
I would like to be able to select the sound device used by Firefox. I have a computer that is used by a community radio station that has three soundcards. One computer is powerful enough to perform all the functions needed at the same time, but the main playback system only works properly when it uses the default sound device. Any web content with audio appears on the station output, but I would like to route it to one of the other soundcards for separate monitoring. All soundcards are PCI interface.
OS: winXP 32bit
Software in use: playout: Zara recording: Adobe Audition other playback: WMP, VLC comms: skype (no camera, no video, works through existing soundcards) stream send: edcast stream check : winamp

It now looks like a motherboard problem. I have built another computer that is a close copy of the one at the radio station, except for the motherboard. Zara behaves as expected, not changing its audio setup back to default devices when restarted. And on the radio station computer, IndieVolume made the erratic behaviour worse, and required me to uninstall it and also reinstall Zara, after stripping out all Zara registry keys because a simple uninstall-reinstall didn't get me back to the original situation.
So thanks for your help getting me to realise that it wasn't a Firefox problem.

hello nev23, i doubt that this will be possible within firefox as this sounds rather like a task that has to be handled on the level of the OS. there seems to be a payware named IndieVolume that apparently offers this feature for windows xp (i haven't tried it myself, so this isn't really a recommendation)...
I have spent an hour tinkering with IndieVolume and it simply doesn't work. It does nothing at all. It looks like it provides a solution to my problem, but it has no effect at all.
Sorry, I've got it now. The plugin container needs redirecting, not just Firefox. In order to control all audio coming through Firefox, how many different plugin containers will I need to redirect?
if the program doesn't work well with multiple plugin-container.exe instances you could disable them generally as it's described at http://kb.mozillazine.org/Plugin-container_and_out-of-process_plugins
