Hey there
My suggestion would be just to first setup with nothing at boot, configure alsaconf only and setup alsamixer and alsactl store on the terminal then save your sound only, reboot and check out the sound with KDE sound system. .You don't really need to use alsaconf more than once.
If you have a second floppy around then make copies as you increase your config. The floppy has limited space available.

BTW, If you do use alsaconf then turn off everything (e.g. browsers, xmms, kafine) before configuration
