Hi

I have no concrete idea, but in general, the usual problems on PPC are
either related with cache coherency or byte endianness. I don't know
of any issue with the latter in ice1724 driver, so likely it's the
former.
Perhaps the ice1724 driver was not even tested properly with the AC97
codec. Do we know of any separate PCI ice1724 card with this codec?

Pavel Hofman.
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 .
Regards
Julian
