I had purchased the FastTrack Pro - I REALLY liked it,
but it would only
work in Linux with USB compliant mode - 16-bit, 44.1 kHz. Is that how
you are using it? To use any other samplerate or to use 24-bit samples
you need the MAudio drivers and special tool, which only work with
Windows and Mac.
Well, if you want to use 96kHz you have to either disable the inputs or the
outputs, then it works (despite the fact that this is rather pointless).
