I just tried the live xubuntu 18.04 and the HDMI display and sound both work perfectly using the Xorg display driver.
I am hesitant to try the upgrade process from 16.04 to 18.04 for fear of losing the use of my computer...

The image displays perfectly, but all the HDMI output devices are listed as "unplugged" I have spent a huge amount of time trying every solution that Internet searching will bring but this has changed nothing. I have tired all available video drivers, including Xorg and NVIDEA 396.26, 340.107, and 384.130. This failure is recent because in the past I could play both audio and video through the HDMI connector. The laptop is dual boot with Windows 10 and the HDMI works perfectly on that OS, although I rarely use it... I am wondering if upgrading my Xubuntu to the latest LTS could potentially solve this issue, but I fear such an update since I depend on this computer and an outage would be very hard for me... Any thoughts would be great. Thanks for making Linux great!
