Could you explain the meaning of the lyrics "Screaming 'cross the waves/you can't hear a sound"

Thee most likely meaning of the lyrics is:

According to the given lyrics, we can see that the writer wants to convey the feeling and mood of despair of a person who is indirectly calling for help, but no one is able to see the signs and help.

As a result of this, the singer probably does not mean the waves in a literal context and could mean that when someone is facing "waves of life", it is difficult to know, especially if the person hides it well.

you could be "Screaming 'cross the waves" as long and as loud as you like, but if no one's around.. if you're all by yourself, alone on the sea then the reason you wouldn't hear a sound is because there is no one there/nearby to respond to your "Screaming 'cross the waves".

Does that make any sense?
