Hint

Here is a hint for RedHat users from William M. Quarles on th LAU mailing list...

I'm using RedHat, but this might work for you, too. Find out which runlevel your computer uses when normally running (usually 3 for text login or 5 for graphical login if you haven't messed with anything).

   grep initdefault /etc/inittab

Then cd to /etc/rc.d/rcX.d (where X is your runlevel number). The directory should be filled with symlinks to scripts that are located in /etc/rc.d/init.d/. The ones that start with K do not get loaded (they are the "kill" scripts that run on system shutdown), the ones that start with S (they run on system startup) do get loaded. The numbers indicate what order they get loaded in. So you need to make a link for ALSA.

   ln -s ../init.d/alsasound SYYalsasound

where YY is 87 on my system (it might be different for Mandrake, I haven't read the script). The alsasound script actually can tell SysV when it should be loaded. To be sure that you picked the right number, run ntsysv. alsasound should be part of the list now. Uncheck it, then save the configuration. Open ntsysv again, recheck it, save the configuration, and the load number will be automatically set to the correct value.

Hint 2

On a Debian system you would do something similar with...

   update-rc.d alsasound defaults #

where "#" is a number described in the previous description.

I think on debian the default runlevel is 2.
