I've got the STAudio DSP24 sound card with Win XP Pro and Vegas 3.0c.  I can't record in 24bit but it records great in 16bit.  I don't get any error messages in 24bit it just doesn't get any signal.  I updated my soundcard drivers.  Is there something with Win XP and 24bit recording?  Also why can I record in Sound Forge 5.0 at 24bit but not in Vegas or Acid?
Thanx
