I don't give up easily but I stubbornly attempt to accomplish tasks without fully comprehending the instructions. So when I tried to get the vac working I ran into a problem. I had Skype on, Audacity up, and vac open. I chose cable 1 in Audacity and compared all the settings. I took a phone call, activated the vac and then pressed record in Adacity. It appeared to be recording but the resulting audio file seemed more like a transmission from another planet. I plan to re-read the directions and try again, but if anyone has already overcome this obsticle, please share your secrets with me and anyone else who may be wondering too.
