Andrew,

Thank you for all of the information... I will clarify the "any", "none"
verbiage is not mine... it was take from voip-info.  I will admit, I
should have done my homework on the motherboard I purchased.  I assumed
that if you buy quality hardware it would just work.  I am not in that
position right now (again my fault).

Would you say, in your estimation, that the sangoma cards deal with bus
level interrupt sharing better than the digium cards?

Then I am confused: 
lspci -vb
Communication controller: Digium, Inc. Wildcard TE210P (rev 02)

Yet I still have sound quality issues due to PCI interrupt sharing.
