ezcap cuts off sound on computer [SOLVED]

I have Windows 8 and I bought an ezcap to convert cassette tapes to mp3 files on my computer and everything worked great. My wife then decided she wanted me to buy her one so she could do the same thing on her computer. I bought her one and the problem I am having is the new one cuts the sound off the computer when it is plugged in. The 1st ezcap I bought allows you to listen to anything on the computer while it is plugged in the USB port but the one I just bought don’t. I tried it on both computers and it does the same on both, the 1st one I bought works fine on both computers. Is there anything I can do to change that?

The more surprising thing is that you didn’t get the problem with your first device. The behaviour with your second device is far more common. Here’s how to fix it: http://manual.audacityteam.org/o/man/faq_playback.html#usb
