DON5408 and Crystal Semiconductor Present Audio Drivers for Crystal sound cards
One annoyance reported by those with newer model Aptivas with the Crystal Semiconductor sound card is that upon every startup the following message is presented: While this does not indicate a problem (see IBM's explanation HERE) this "informational message in error message format" has bothered many. Previously there was no way to eliminate this message, however several users have noted that after applying the updated audio drivers from Crystal this message no longer appears.

In addition to removing the "cannot load..." message, the latest drivers from Crystal add the following functionality: NOTE: While Crystal indicates that these drivers "should work with most implementations of our chips" and this has been confirmed by Aptiva owners, these are *not* IBM supplied nor supported.
