Resampler not producing audible outputs

[LovelyA72]

This resampler is not producing audible outputs regardless of Windows or Ubuntu.
I am having a few educational guesses.

1. timeGetTime() function? This is a Windows-only function and I am using a substitute here. The substitute might not be appropriate.
2. I replaced _fpclass() functions with Linux's fpclassify(). The code is trying to exclude NaN, + Inf, -Inf, denormal which all of them are doable with fpclassify(). Might be due to my incorrect usage of fpclassify()?

Update 1: Seems like timeGetTime() function is only being used as a performance counter in main.cpp. So that's probably not the cause.

Update: Turns out that the process of generating dio, star, and platinum are the issue. I am not sure which one is causing the issue but the resampler will generate audio normally when dio, star, and platinum files are generated from SpaceWorld are provided.
