Is TDM2 a music file or a sound file?
I ask, because you are preloading TDM2 and the manual states:
Music is never preloaded, since music tracks often involve a large download size, and it is not usually important to have music play with as little latency as possible. Music will still stream from the server while playing, but if the latency is important, the Preload action can be used to load it in advance of playing.
