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.
