This is correct. But, if you have more than USB sound device, it's a bit arbitrary which one gets which id. And, if one is removed, your id can shift. I'm told, though I haven't worked out how to do it, that using udev is the only way to lock a particular USB sound device to a particular alsa card id. I'd love to see some examples of how this can be done with udev, but haven't found any.
