I've been playing around with the Appliance on an HP 8000 Elite which is a dual 
core machine, probably similar to the one you are having issues with.  The 
onboard soundcard is a Realtek ALC662 and like you I've had issues getting it 
to work with Rivendell.  In the end I gave up and went for the option of 
installing a Soundblaster Audigy 2 card which has worked without issue.  The 
onboard soundcard is now disabled in the bios.

The HP dc7800 and dc7900 machines have ADI Soundmax sound cards onboard and 
these work great with Rivendell so it must be something with the Realtek.

Just one other thing for you to try before giving up totally on the onboard 
audio (I didn't do this - only just thought of this) is to try changing the IRQ 
of the onboard sound in the BIOS.  This can be found somewhere in the right 
hand menu of the bios.  This might just sort out the problem.  I've known of 
IRQ settings on HPs stop things from playing nice.
