This is evidence that rtirq is being started *before* alsasound. Your
boot/init order is thus wrong.

Check also
  ls /etc/rc.d/*.d/*alsa*
As you can see, the main question is whether S88rtirq is after S??alsasound.

This is pretty legal. If you can see "irq 5" there, so can rtirq. But note
that this /proc/asound/cards contents is only available after ALSA is
loaded.

Sounds reasonable.
