Display port audio recognized in live mode but not after installation

[netpage]

After a powercut, my Display port sound device was not recognized. I tried troubleshooting but nothing worked. I then ran a 'live USB' of Ubuntu 22.04, Ubuntu 22.10, Xubuntu 22.04 and during live mode, all OSes recognized the Display port sound and sound worked. But after installing it, it was no long available.

Pulseaudio is showing in the bug report as, before sending the report, on a vanilla install of Ubuntu 22.10, I ran through one more troubleshooting guide that installed Pulseaudio. The issue was not solved, and I am sure it is not due to pulse audio.

Please let me know if you would like me to test anything. Thanks.

FYI, today, I tried installing Elementary OS 7 on the same computer. After the initial installation, HDMI Audio was recognized. However after the second (I think - or 3rd) subsequent system update, HDMI Audio disappeared from the sound settings.

Not sure if this will help you track down what update is causing this?

Cheers

When I upgraded to 23.04 the HDMI Audio option appeared and is now working OK. Thanks.
