I run my UA-5 to Sound Forge.
Make Sure you have the Bit, and Sample Rate matching. If not, you will have to close out the Program, and also power off the UA-5, and change the setting on the UA-5. Make sure all of the Settings(Digi/Analog input, Sample Rate, ect) on the UA-5 are correct, because you cannot change them while the UA-5 is on, you have to have it off, for the changes to take affect.
Make sure you turn on the UA-5 BEFORE you open up the Computer Program.
Make sure you have the correct input selected(UA-5) in your PC Program.
