Useless command lines in "/usr/local/etc/init.d/alsasound" of alsa.tcz package?

[littlebat]

I don't know if it is necessary to "set Master -12dB" after has seted "set Master 75% unmute", there are many such lines in this file.

I have read "man amixer", and read the similar file such as "/etc/init.d/alsa-utils" in Debian Squeeze. Found it seems no necessary add "set * *dB" after has seted "set * *% unmute".
Isn't it?
