I'm hoping someone can help me with my sound issue. I installed a fresh version of Ubuntu 22.04 on my laptop (AMD Ryzen 7736 with Radeon graphics). Sound doesn't seem to work. At first, the settings just showed "Dummy Output" for my Sound Output Device. Trying out the following:

I now see "HDMI/DisplayPort-HD-Audio Generic" as the Output Device. However, the sound still isn't working.

Of note: the pulseaudio service is dead
