Cant't get audio from a Mackie 1202MS thru the ADVC-100 is connected to the computer with firewire. If I plug in the Mackie direct to the sound card (Audigy SoundBlaster, the one that comes with the Dell computers), I get low audio levels. I have to pump up the volume all the way up to get a decent level. I'm using an Audio-Techina shotgun mic (with battery).
