Hello Dawn,
Please use the following steps to identify your sound card and I can link you to the device driver for your sound card.
Click Start in the lower-left corner of your screen, or navigate to the Start Screen
Locate the Search box in the lower-left corner of the window that appears. Windows 8 users can type on the Start Screen. Windows 10 users can use the Search box on the taskbar, next to Start.
Type dxdiag and press Enter.
Your sound card is listed under one (usually the last) of the sound tabs at the top of the window.
