"Dummy Output"

To start off, I have an HP 14 inch laptop model ep0000 with an Intel core i3-N305 in the Alder Lake-N architecture family, 8gb of ram, 256gb WD NVMe storage, integrated graphics, and Realtek HD Audio.

Currently it is running pop!_OS 24 and used to run Windows 11 and the sound works fine. It appears anything before Ubuntu 24 does not have sound drivers specifically for my laptop and I am really bummed about this because I really want to use Zorin OS on it. Going into a live disk, I can find in the settings that all I have is "Dummy Output". Is there anything I can do to fix this so I can use Zorin?

aplay -l displays "no soundcards found..." to start.

This is when I run uname -a and sudo lshw -C multimedia.

Feedback would be greatly appreciated to make things work.
