The snd-seq kernel module does not autoload (for some unknown reason,
probably related to udev). A workaround is to do this as root:

  /sbin/chkconfig alsasound on

This will enable the alsa startup script which will load snd-seq on the
next and subsequent reboots (or without rebooting do
"/etc/rc.d/init.d/alsasound start").
