Sound level issues MAC

I installed Minecraft yesterday. I can't remember if the sound issue was here when I first played to, maybe I didn't mind at the start.

-The walking/running/jumping sounds on grass and rocks are so low or absent
Note that the walking/running/jumping sound on gravel are present

-The sound occurring when an item breaks is absent

-Some sounds, as the "click" occurring when the in game menu is closed is far too loud.
