phil_m, they are not.
BigChas52, I don't know wether it is or not since I just got it, because with this UX2 soundcard I could use an XLR microphone rather than the USB ones I've used before. So there is no way for me to check either, really...
And yes, I do get sound when I play the guitar and the input set to instrument
I did see someone that got it to work by putting the input to Mic 1 or 2 and then quote:"Went into the Drivers Console..." but I can't find anything about a driver console..
