Damn, I just realized this : http://www.vesalia.de/e_aca630-25.htm
Which clearly says : Please note: The ACA 630 does not work with A300 boards!
I wrote several months ago about the ACA 630 being incompatible with A603, having no sound with some WHDLoad demos.. I thought the A603 being defective so I bought the A604... no luck.
So I guess that was it : I just discovered/realized I have a A300 board :-(
Is a software update planned to fix this incompatibility ? Is there an hardware patch I can do for it ? (on the A300 board)
Or am I screwed for real with it? :-(
Best regards from Canada!
