Any plans to look into the X5000 CMI8738 Sound Card issues ?
The CMI cards seem to be the the models in greatest supply .
The PCIex1 version issue is probably related to the Asmedia 1083 bridge chips (Revision 1) but may be able to be be overcome in the driver. Case in point I have an Envyht24 pciex1 card with an Asmedia 1083 revision 1 bridge chip that works on my X5000 with AmigaOS 4.1FE with no problems.
The PCI CMI8738 cards (which do not have a bridge chip) also have an issue as some models work and others do not.
I am using a PCI CMI8738 in my X5000 with no problems with AmigaOS 4.1FE
Or could the the problem actually be with some X5000's ? and not with others ?
