Did you by any chance acquire a USB midi device recently? I find that
if my BCF2000 is plugged in at boot time it shows up as hw:0. Which is
annoying with those programs that look for the first available alsa
device and take for granted it will have a DAC on it. Anyway, the
numbering is determined by the order the kernel finds devices, and you
cannot take for granted that the kernel will discover your devices in
any particular order.
