If you want...
You know normal people don't keep on deleting their config files all the time, usually sound setup is done in a few seconds only once and never after that, so it doesn't really matter which device is selected by default usually...
But it's your day of luck, sdl2 thought about people like you and it knows about selecting a default device instead of just the 1st one, so that's what I'll do now. I can't test it now because I don't have any pc with 2 soundcards, maybe the mini but it has no raine for now because of a very small disk... I might test this later then. (but I don't guarantee sdl2 default will be the one in your desktop, but maybe !).
edit after trying : no luck, the mini has only 1 soundcard detected, I got an old pc with 2 but this one hasn't been powered on for 3 years now and everything is too outdated on it to test something like that ! Oh well, you'll test that next time... ! Anyway I have no pc with 2 soundcards and windows installed on it !
