Does the interface work with another computer or OS? Which input are you
using? Instruments should go into input 2 and if it's a stringed
instrument with a pickup and no preamp the Hi-Z button should be
activated. What kind of instrument are you using it with? Could you test
with something else like a microphone?

The interface is recognized by your OS and you can select it in Ardour
or Audacity so I don't think its a connection issue. It sounds more like
a setting on the interface itself. Or a defect but these are very sturdy
devices, I've got an UA-25 that I bought back in like 2005 and it still
works perfectly.
