logitech sound card ruined normal audio

[murray_94]

My laptop only has one audio port so I bought a usb sound card so i could use my headset with a mic. But when i unplug the sound card and just use my headphones the sound has an echo. Did it change my audio drivers or something? How can i fix this?
