I have no Sound on my computer

I have no sound on my computer through the turntable
I have only hooked up the usb cable
do I need to use the rca plugs also to get sound?
everything else has sound but for some reason when I try to listen to a record it has no sound
I got this for Christmas and am trying to put some vinyl records onto cd
this is a frustrating piece of equipment
any help or suggestions would be appreciated

When you plug in a USB device like this your computer hands over control of all sound services to the USB device - both input and output. Since you USB TT doesn’t have a set of speakers, you then don’t get any sound from the computer (not even the normal Windows sounds).

All you need to do is to get Windows and Audacity to retarget the sound output onto your PC’s on-board soundcard. In Windows use Control Panel > Sounds and Audio Devices > Audio > Sound Playback - in Audacity use Edit > Preferences > Audio I/O > Playback Device - you may need to close and restart Audacity for the change to take effect.

Many folks fall into this bear-trap when they start out with USB/Audacity - I certainly did !
