I have aphantasia, but it doesn't extend to imagined sounds. It's almost the opposite really. I can imagine a variety of sounds a ball might make hitting a table depending on materials involved. When I've got a song stuck in my head it tends to be quite detailed. Full instrumentals and all. That doesn't mean I have perfect recall of songs or music to any degree. And it's not exactly voluntary. I can't tell you the full lyrics to any song off the top of my head. But when I get a song stuck there, I can "play" through it all and pick out details.
