How to enable sound on TV via DisplayPort on HP 8440p

The following worked for me when connecting to an LG TV: -

In Windows 10 or Windows 11, ensure that the following software drivers are already installed: -

IDT High-Definition (HD) Audio Driver Version 5.10.6257.0; 6.10.6257.0 Rev. (sp46721)
Intel High-Definition (HD) Graphics Driver with Turbo Boost Technology Version 15.22.59.64.3268 Rev.A (sp64360)

In Windows 10, when the above mentioned software drivers have been installed: -

Shut down the PC and the TV.
Connect the HDMI cable (and DisplayPort-HDMI adapter) to the TV.
Switch on the TV and restart the PC.
Open "Settings" and select "System"
Under "Sound" and "Output" and "Choose your output device", check to see if "LG TV (Intel(R) Display Audio)" is an option.
If it is, and not already selected, select "LG TV (Intel(R) Display Audio)" and close "Settings" and reboot the PC.
Otherwise, open "Settings" and select "System"
Under "Display" and "Rearrange your displays" click on "Detect" and then click on "Identify".
Close "Settings" and reboot the PC.
Open "Settings" and select "System"
Under "Sound" and "Output" and "Choose your output device", if not already selected, select "LG TV (Intel(R) Display Audio)".
Close "Settings" and reboot the PC.

In Windows 11, when the above mentioned software drivers have been installed: -

Shut down the PC and the TV.
Connect the HDMI cable (and DisplayPort-HDMI adapter) to the TV.
Switch on the TV and restart the PC.
Open "Settings" and select "Sound".
Under "Sound" and "Choose where to play sound", check to see if "LG TV" is an option.
If it is, and not already selected, select "LG TV" and close "Settings" and reboot the PC.
Otherwise, open "Settings"and select "Display".
Under "Display" and "Select a display to change the settings for it", click on "Identify".
Close "Settings" and reboot the PC.
Open "Settings" and select "Sound".
Under "Sound" and "Choose where to play sound", if not already selected, select "LG TV".
Close "Settings" and reboot the PC.

Hope the above helps.
