I don't have a perfect solution for this, but being in a similar situation with my hardware, I've grown accustomed to keeping the USB audio plugged, and only plugging in the camera when I need it; therefore generally *after* the audio-only device. This way the USB audio device is always rsnd/1 here. This may not be what you're looking for... there are also USB hubs with physical on-off switches that I've used for my USB camera this way. YMMV
