Description zodomaniac 2019-11-29 06:50:37 UTC 
https://www.youtube.com/watch?v=WBWB81EOVQQ This is the demonstration of the sound bug on Windows with speaker configuration 5.1: high-pitched sound effects and no MIDI music played.

One small question: did you re-opened audio after loading of SFX? I did a small test on my end and:
- Open audio with 2 channels stereo
- load any SFX
- Close audio (but don't unload library)
- Open audio back, but with 6 channels
- try to play that SFX
- it will play faster

Yeah, to avoid this dirt, you probably should reload all chunks after audio reopening.

(In reply to Vitaly Novichkov from comment #1)
I cannot select 5.1 configuration on my sound card to test this, and in fact it was not me who discovered the bug.
Comment 3 Vitaly Novichkov 2019-12-18 13:35:17 UTC 
Anyway, I think, the bug is on a side of the game because it did the audio output switching without reloading of SFX chunks. I have reproduced the same glitch on Linux where I did the closing and opening audio and with trying to play the same SFX chunk without reloading.

Youtube vids won't help.  Please provide a minimal test case so
that we can reproduce.  Will wait for about a week before closing
this.
