Comment 9 for bug 592016

What has come up is that this may be related to alsa-utils

On machines where alsa-utils is installed, but alsamixer never run then sound on boot is fine (not muted and or set to 0
Once alsamixer has been run once, then on reboot sound is either muted @level 0 or just set to level 0

maybe in question is this line? line 385
mute_and_zero_levels "$TARGET_CARD" || EXITSTATUS=1

(removing the line or setting the 1 to 0 and sound is always fine on boot, even is alsamixer has been used
