Connect a device with HDMI support to the HDMI-
Out port BEFORE attempting to play audio/video
sources through the device.

playback device will not revert to speakers until the
computer is restarted (if you do not wish to restart the
computer then go to the Sound control panel and select

HDMI Audio Support
Note that NVIDIA GeForce 8800M GTX/ 9800M GT video
cards do not support High Definition Audio through HDMI.
When connecting a GeForce 8800M GTX/ 9800M GT vid-
eo card to an external display (using an HDMI cable), it is
recommended that you use a third party video application
(e.g Power DVD) that provides appropriate audio decod-
ing to play DVD's etc. Alternatively you can output audio
through an alternative source to the HDMI connection.
