It is oversimplifying things that a single compound mediates complex human behavior. To nuance things a bit, there are more neurotransmitters and modulators that mediate feelings of pleasure, as you already indicate.

• Dopamine, indeed, is associated with feelings of pleasure, and most notably that in response to reward. It also mediates reinforcement, and unfortunately the euphoria associated with addictive dopaminergic psychoactive drugs, like heroine and cocaine.
• But there are more neurochemicals mediating pleasure, such as serotonin, that is increased after working out ('runner's high') and after exposure to sunlight, fore instance.
• Endorphins are a group of protein neuromodulators with a diverse set of functions, from killing pain to the feelings of bliss after sex.
• Lastly, there is oxytocin, the 'love' hormone. We produce oxytocin when we’re excited by our sexual partner, and when we fall in love. So there is more to pleasure than dopamine alone.

What you are referring to, an absence of pleasure, is referred to as anhedonia, this is not simply due to an absence of dopamine, but is one of the possible symptoms of depression and other mental illnesses, like schizophrenia and bipolar disorder. It can even show up with Parkinson's disease, diabetes, coronary artery disease, and in substance abuse. While schizophrenia and Parkinson's are intimitely linked to dopamine, others are, apparently, not.
