I have my hdmi cable connected to the lcd tv and have a picture but no sound. So I right click the speaker icon to look for the hdmi option and it's not there. I find intel hdmi in devices and click update and it says its working fine. I upgraded from vista to Seven and I'm sure it used to offer the hdmi as an optional default. What to do?
Depends on the video card you have and it's capabilities. Some Video cards have their own built on the video card audio for HDMI only. If this is the case you need the latest drivers from the video vendor (AMD (ATI Radeon) or NVIDIA).
You failed to list your PC spec's (e.g. there are a lot of Dell Studio models) and your video card. We can't give you a specific answer without that.
But, go to the Control Panel/Hardware and Sound and finally the Sound panel. In the Playback section, is the HDMI audio listed as a playback device? If it is, select it as the default playback device and you should get HDMI audio. If there is no icon for HDMI Audio, RIGHT click in an empty are in the panel and check both the "Show Disabled Devices" and "Show Disconnected Devices". If the icon now shows up you can select it as the default playback device. If it still does not show up, most likely the driver is needed.
