After clicking playback devices only speakers comes up , conexant had audio default device
Expert:  *ElectronicsTech replied 3 years ago.

If the TV has a "DVI/HDMI" port do not use it. Use a port for HDMI only.
Try this please>Go to Start>Control Panel>Sound>Playback tab. Make "HDMI" the default device. 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. (This applies only to Vista & 7.

There is only speakers on the list as default nothing else
Expert:  *ElectronicsTech replied 3 years ago.
okay, sorry about that. Which operating system do you have on your Dell? xp, vista, 7, etc....

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. The graphics driver is the driver for HDMI audio, not the regular audio driver. 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).

2. Try disconnecting and then reconnecting the HDMI cable.

3. If you are using Windows Media Player or Windows Media Center but get no HDMI audio even after it is selected as the default playback device, go to
Control Panel>Sound>Playback tab>Audio/Playback device>HDMI>properties>Advance>Exclusive Mode and uncheck "exclusive mode".

4. Try a different HDMI cable.

5. Try a different HDMI port on the TV.


If HDMI is missing from Sound in the Control Panel and there is no audio through HDMI, download and install the latest Intel video and IDT audio drivers from to resolve the issue.

  5. Click the desired driver for your system displayed in the File Title(s) column to display the download page.
