It does it because somehow the fps fluctuate by 0.1-1 frames even when the game is turboing well over 70fps (don't pin me on that exact number though) I can easily hear it in the screen with the Monado (titlescreen). It completely vanishes with Audio stretching off.
I have audio stretching turned off by default on the latest dev build and I still get the occasional crackle. It happens regularly on certain parts of cutscenes (like when the opening cutscenes switches to Shulk's narration for the Battle of Sword Valley it always happens) and occasionally on other parts too (for example when the opening cutscene shows Dunban cutting down Mechons the audio sometimes, but not always, crackles during it).
Here is a a clip of the crackle happening when Shulk starts the narration for the Battle of Sword Valley: https://webmshare.com/VGRxV
That's a very mild case of crackle though. The aforementioned cutscene with Dunban cutting down Mechon has way worse crackle whenever it occurs there.
This happens to me with both "XAudio2" and "Cubeb" Audio Backends and audio stretching not being enabled while using HLE (I attached picture of my current Dolphin Audio settings to this post). All my other settings are the same as the ones shown in the opening post pictures except I turned off "Speed up Disc Transfer Rate" from the .iso settings 'cause the 5.0-6671-x64 build of Dolphin doesn't seem to require it anymore (I tried turning it both on and off just in case but it had no impact on the crackle).
