This gets very frustrating. As much as I am a fan of Dell, it’s really aggravating when they don’t provide a driver for one of their systems.
In this case, the Dimension 3000 desktop is configured with a Sound Blaster 24bit card SB0410 done in partnership with Dell. Unfortunately, Dell doesn’t provide the driver for it on their support site – only the one for the non-existent onboard sound. Morons.
In case you encounter this issue, here is the link for the SB0410 drivers:
Creative Sound Blaster Live! 24-bit and Sound Blaster Audigy LS driver 1.04.0055
Just in case that one is dead, here is a direct link to download it from me.
