Query: Poor mic compatability

I bought this to replace an m audio fast track that had developed an annoying intermittent shriek through headphones. On installation I found that this unit didn't offer compatibility with Skype and had poor preamplification of my Shure SM 48 via the XLR input. My onboard sound software Adobe Audition did not register the mic output at all, even though the driver options were set correctly, and the supplied Cubase registered very low mic volume, even though the mic input was turned to maximum. My choice was to return the unit or purchase a mic preamp, which I was loathe to do.....Seeing the m audio had good enough recording volume and was compatible with Skype I have decided to by another unit from from m audio and return this unit to Amazon.
