Hi - I recently downloaded Logitech video camera and about that time the sound on my computer quit working. When I open the sound board it says it is using my USB audio device and doesn't offer me any other choices. Can someone tell me how to fix my regular sound? Can't hear videos when I try to pay them. Thanks

Have you tried to see what device manager is saying about your sound card. Is the drivers still there and is the sound card enabled?

Try to uninstall the sound card and reinstall the drivers to seeif it will repair it!
