Custom sounds in a resource pack

Hey, sorry to bother with such a basic question, but Im kinda lost. I tried following a few tutorials and even downloaded a template, but** I cant get my custom sound to actually play in the game** (the command isnt highlighted in red, the game knows the sound should be there, but i cant hear anything)
The structure of my pack is as follows (version 1.21.4)
-pack
          -pack.mcmeta
          -assets
                    -minecraft
                              -sounds.json
                              -sounds
                                        -soundfile.ogg
