man, foobar is music player I need FLASH PLAYER which is able to do
the same thing - choose which soundcard to use for audio output.

if you dont know why I need to use flash player, check my previous

and yes i would use default card for firefox its not important which 1
I use, but then i need to change audio card for the game my brother is
playing (swat 4 stetchkov syndicate). it is not possible in the game
as well, as far as i know (i tried to find it).
