Welcome to the Magix Sound Forge users community @Johnny-Spivey.
In Windows sound settings, confirm your desired input source is set as the default 'Recording' device. In the Sound Forge, go to the "Options> Preferences> Audio" menu and select the desired 'Record' device . The Microsoft Sound Mapper and Windows Classic Wave Driver are usually trouble free with internal sound cards. An ASIO device driver is usually not needed in Sound Forge.
