If arecord writes only the .wav header it means that your interrupt
routing is broken - if it were a mixer settings issue arecord would
capture silence.  You can confirm this by checking /proc/interrupts
and see that the interrupt count for the Audigy does not increase.

This is going to be an issue with the upstream kernel not ALSA.  Try
booting with "acpi=off".
