I agree, this value is bogus. I just fixed the code to return exit code 
99 as described in init/00main:

There are two ways to fix this issue for your distro:

1) modify the script which calls alsactl and add a check for code 99
    (it may ignore this exit code) - assuming that patch above is applied
2) change init/00main - EXIT="99" line to EXIT="0"

But from your gentoo bug, I guess that your system don't save the last 
soundcard state to /var/lib/alsa/asound.state correctly - it's looks like 
a bug in the init scripts for your distro.

Or it might be totaly different issue - could you send me your 
/var/lib/alsa/asound.state file and file test.state generated using 
'alsactl -f test.state store' command?
