Sometimes my TV card becomes card0 and after a reboot it is card1 again (like it should be). Fortunately that is very rare and I did not feel a strong urge to solve that.
You can set permanent device numbers using files in /etc/modprobe.d/<file>.conf I think... (often used for NICs, why not for audio devices?)
