Alright well as seeing it has the Sounds file and the Music file, all you need to do is do these codes. didn't take long to figure it but sharing it 
Start-Up music since it doesn't have one:
Code:
if(!lowMem)
{
nextSong = 0;
try
{
nextSong = Integer.parseInt(getParameter("music"));
}
catch(Exception _ex) { }
songChanging = true;
onDemandFetcher.method558(2, nextSong);
while(onDemandFetcher.getNodeCount() > 0)
{
processOnDemandQueue();
try
{
Thread.sleep(100L);
}
catch(Exception _ex) { }
if(onDemandFetcher.anInt1349 > 3)
{
loadError();
return;
}
}
}
And now for the enabling of sounds since the sounds.dat doesn't even exist to load (if you have it Server sided already you wont hear anything well this fixes it).
Code:
if(!lowMem)
{
drawLoadingText(90, "Unpacking sounds");
byte abyte0[] = streamLoader_5.getDataForName("sounds.dat");
ByteVector stream = new ByteVector(abyte0);
Sounds.unpack(stream);
}
Enjoy.
