When i installed a new belt for my NST underdrive pulley, my mechanic said if it made any squeaks when starting up i would have to tighten my belt.

Im guessing the same would apply to the noise you may be hearing if its the belt. It is just slipping and getting abit loose, but once it warms up it grips better.

You could try tightening the belt first if you have much tightening left. You can see how much more you can tighten on the silver/grey leaver with the bolt just above all the pulleys. Otherwise as someone said early you should just replace the belt they are pretty cheap.
