Yes the HDMI port also supports audio. You have to put the HDMI Cable into your external monitor first and then into the notebook.
To set the audio device for using HDMI, follow the steps bellow:
- Click Start
- Control Panel
- Hardware and Sound
- Sound /Digital Output Device (HDMI)
- Click the Set Default Button
If this does not work, please notice that some HDMI monitors may not function properly, because the port operation of all HDMI monitors has not been confirmed.
