[KDE Neon] No audio

I installed KDE Neon to shift from Windows 11 after the stupid Recall feature and all other bloatware. Everything seems to work fine except there is no sound. I am a noob and hence would appreciate if I could get some help.

I tried following what was said in this post. However, upon running the PulseAudio command, I got an error saying that PulseAudio doesn’t exist.

Does KDE Neon have it’s own software now or do I need to enable/install PulseAudio? If yes, how do I do it and if not, what should I do?

The post you’re referncing is out of date. Meanwhile pulseaudio has been replaced by pipewire (which is not specific to neon), so that message is correct.

I think the most likely problem is that you have multiple soundcards and the system selected the wrong one as default.
What do you see if you open System Settings and go to Sound?
