Hi! Thanks for that help but in the meantime I installed the v5.5-rc7 kernel using ukuu. It gave some warnings (see attached) but still booted.
After boot, the HDMI/Display port 2 displayed as "plugged in" in the pulse audio volume control and the audio did come through the HDMI cable and out the TV. Here's the strange part : I then booted on the previous 4.4.0-171-generic kernel and removed the v5.5-rc7 and rebooted. At this point the HDMI/Display port 2 displayed as "unplugged" but the sound still worked over the HDMI connection to the TV. I have no idea why this is or if it will continue to work. I've attached screenshots. Any thoughts would be welcome. Cheers, Bob On Wed, 22 Jan 2020 at 09:30, Daniel van Vugt <daniel.van.v...@canonical.com> wrote: > The kernel packages have no dependencies.

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!
