Since this is not the newb section I can say with some impunity..RTFM! But, seriously do, we none of us was BORN with technical knowledge.
The Book will surely give you detailed instructions on how to install the Audio Box but generally DON'T plug it in! First job, download the latest drivers for the AB from Presonus taking care to get those applicable to YOUR OS and 32 or 64 bits (hope you ain't still 32!) Save the drivers to desktop for now. Almost certainly, run the driver dld and follow the instruction TO THE LETTTER! At some point as a rule you will be prompted to plug in the A box and then 'other stuff' will occur.
If all that goes tickerty, next step put your headphones on and play a radio station or YT file. No sound? You now need to delve into Windows Sound menus to setup the box as "Default Record and Play Device". You need to get to this point before you can proceed further. Assuming you have, install the Presonus recording software. Is that Studio One? Can't help with that a lot. I have the freebie but have not had a chance to play. If another bod does not come to our aid soon I will have a look.
