However, audio output from the onboard audio controller or the external sound card will be disabled when HDMI output is activated. If no need for HDMI output function, set the onboard audio controller or the external sound card to be the default Sound Playback device to obtain audio output from your system. For more details, refer to page 14. Expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer. 1. Turn off your computer and unplug power supply. 2. Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case. 3. Place components on a grounded antistatic pad or on the bag that came with the components whenever the components are separated from the system. The card contains sensitive electric components, which can be easily damaged by static electricity, so the card should be left i...
