We see these questions a lot. It is primarily because your device does not have it's ASIO driver installed. While Windows will use the device as a class compliant playback device using Windows Audio Drivers, you can't hear audio playback or recordings because Studio One relies on a different codec than what Windows provides. Studio One relies on something called ASIO which bypasses the Windows Mixer and provides lower latency audio recording and playback.
The AudioBox USB (and all other PreSonus products) no longer have discs in the boxes, and Windows doesn't know that we require an ASIO driver. There is a registration card in the box that comes in the bag with the Quick Start Guide (that unfortunately most folk's disregard) and just plug the interface in and end up like we are here.
Registering the interface will present you with the software download for the application and for the device driver. Device drivers are also available to anyone on our download page here: https://www.presonus.com/support/downloads
. Just select your device and download the latest release. Install the software, a reboot may be necessary.
Then follow the quick start guide to get going. All of our product manuals include walk through setup instructions to get you up and running with the software as well.
