Pulseaudio - output to all devices?

Heya, I use Pulseaudio, and I frequently use a USB audio device. However I find that when I plug the device in, I have to go into the settings (eg. pavucontrol) and switch output over to the new device from the default built-in audio. What I would love is for Pulseaudio to just output to EVERYTHING. I realise it'll waste a bit of CPU time sending audio to the hdmi monitor and the built-in soundcard.. but eh, whatever. There's an i7 CPU in this machine, it'll cope. Any suggestions on how to tweak it to do this? Cheers, Toby PS. Please, no Pulseaudio hating comments. I quite like it, and think it does a good job. YMMV, but keep it to yourself.
