No sound, just static

I have an ion profile pro and a MacBook Air with MacOS Sierra and when I try to convert an album the sound is just static. I have checked the audio settings suggested with no change. I also downloaded the most resent version of the software. I did test it on my old laptop (MacBook) with an older operating system and it did work so I don't think it is the needle. I would use my old laptop to do the conversion but it does not have full functionality of the trackpad. Can anyone help?
