![]() ![]() A few people with Intel graphics had better results by uninstalling the graphics driver, rebooting, and letting Windows look for a driver (instead of downloading the driver from the Dell support site). The graphics driver is the driver for HDMI audio, not the regular audio driver. ![]() If there is still no option to select "HDMI' as the default audio playback device, try re-installing or updating the graphics driver, or even try an older version.XP does not have "show disconnected devices". If "HDMI" is not there, right click in the white area and look under "Show Disconnected Devices" or "Show Disabled Devices" and see if it is there. Go to Start>Control Panel>Sound>Playback tab.To set, repeatedly press Fn+F8 (or ctrl+alt+F4) to cycle through the settings (laptop display only - laptop + projector - projector only). Some models do better if the projector is set to be the primary display. (Optional, some people close the laptop lid immediately after hitting the power button but I am not sure why. Adjust the projector settings to receive HDMI audio if any. Turn on the projector and select the HDMI port you are using.If the projector has a "DVI/HDMI" port do not use it. Connect the HDMI cable to the computer and projector.HDMI audio is extremely finicky and seems to usually need a reboot. Every time you try a different solution you should reboot the computer.Later, after you get your HDMI audio working, if you disconnect the cable while the computer is running and lose your audio, try closing and then re-opening whichever program you were using that generates audio. ![]()
