change device output for realplay

[Andras Lorincz <andras.lorincz@gmail.com>]

I have 2 soundcards and I can use both with apps like xmms, xine, etc.
because they allow to set the output device. Sometimes I want to hear
radio using realplayer but not on the default device, and it doesn't
allow to set the output device. I can manage this if create .asoundrc
with the following content:

pcm.!default {
        type hw
        card 1
}

ctl.!default {
        type hw
        card 1
}

but this incurs that I have to create the file and restart alsa. Is
there a simpler way?

PS I'm using alsa.
