We are not using the onboard soundcard, but rather a second one.




I think that at this point, we need a lot more information than we've got. For a start, what is the second soundcard? Internal? External? And, has anything else about the machine changed? Usually if a soundcard fails to be recognised, it has more to do with the operating system and drivers than the hardware - but it still helps if we have a better idea of what we are dealing with.
