So you're playing games with the system, literally. Any chance that the game controller (providing one is attached), or your own actions, are changing the volume? If so, the question then becomes whether or not it remembers last setting, or instead always defaults to a setting. A setting which can change, but only changes one way, once it's changed that one way, then it stays at that point until that manner is used to adjust the volume again where it would stick.
So, it would seem that some better characterizing of these phenomena would be helpful to know. I suspect that you may find that once you do characterize in more detail, you'll likely discover the ways things are working, be they desirable vs not.
