As distributed, no change: still not seeing any activity on IRQ 5. I'll play around with it some over the next day or so.
Observed: the alsa "snd-sb8" driver works fine. Question: how does IRQ setup differ between the sb8 and the es18xx drivers? If I can find some time, I'll try to figure that out...
