The second board mentioned , the Aeon Cyrus ,uses a P5020 so is cache 
coherent .
The problem may be in the initialization of the sound card as on some 
boots with my board , an Acube Sam460ex, it works perfectly.  I have  
tested a CMI8738 pciex1 sound card which works perfectly as do USB cm108 
based external cards .

I also have a PCI ice1724 version of the card  (never used in this 
machine) as well as 2 different pciex1  ice1724 cards with the codec .
The Sam460ex only has 1 pci slot normally used for the SATA card and 1 
shared pcie or SATA II.
I could test with  the pci card by booting from USB .
So either configure as 1 pciex1 slot or 1 on board SATA II .
I am helping to test the onboard sata-dwc but am happy to test any ideas 
for a solution to the audio issues as well.
Will mean reconfiguring my machine back an forth but worth it for 
solutions in both areas .
