You can address ALSA devices by name as well,
in that case you don't need to worry about the card
number.

For example, you can look at the output of 

aplay -L

and for amixer use the device names with the -D option
instead of card number with -c option. Longer to type,
but more stable for use in scripts. 

Here are some references:

Have fun (and unambiguous audio device references)
