Oh... now you mention it... Are you referring to that "System Internals" option in Spybot's Advanced Mode?
It's not a toy though. Even I'm not familiar with that function, but I have a general view of what it does. Well, it searches for invalid paths [in your system] or somewhat like that and it offers to clean it. I'm guessing Spybot is telling you that these paths to SoundMax (maybe the options settings) are invalid.
It's not a big deal if you fix it or not, as it will not make a noticeable impact on your machine.
