Cannot hear recording over USB Mic & Headset

[steve]

This is not a reply, but again similar problem I am experiencing with me too.
I use USB based Behringer U-Phoria Studio Recording device. I import my track for song into Audacity, and the singer sings while recording.
Everything ok, vocals also recording fine. But unfortunately I am not able to hear the vocals singer (sound of his singing) in my headphones.
I tried all options but no results.
