Any Help with Sound Modding SA2?

[Speedist]

I've been attempting to make a Sound mod for Sonic Adventure 2 and I can't seem to properlly loop the modded track. I've so far have been using Audacity and the PES Sound File Converter 1.8.The weird thing is when extracting the original track, importing it to Wavosaur which I've used to loop a mod for TF2.. theres a long pause that appears. but In Audacity. theres no sign of a long pause..And I haven't yet figured out how to make it loop. and yet I checked "Save ADX file with loop from start to end" in the PES Converter but checking in sound test. and when the modded track reaches the end. the disc stops spining like I hit stop. I'm starting to feel like I'm not using the correct programs to make the sound mod even though it seems I am. Anyone who can point me into the right direction to fix the loop problem?

I've used AdxEncoder.exe with great results for looping before.
