I know it is not officially supported board but maybe someone has a solution. My issue is although I had success installing MorphOS since ver 3.17 I never managed to get sound output and tried multiple cards in Pcie slot. Sound works fine in AmigaOS. It is something to do with PCI bus in this motherboard and morphOS. I was hoping the issue would be solved with new release but unfortunately it is still there. Maybe there is a custom install for SAM460LE. Any suggestions are welcome.
