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 . Regards Julian
