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).
Try the following steps and see if the issue is still present:
1. If you haven't done so already download and extract the latest development version in a NEW folder *do not overwrite an existing installation*, you can find it at the top of the download page
2. Download and install the latest nVidia Driver for your GPU (found here http://us.download.nvidia.com/Windows/391.24/391.24-desktop-win10-64bit-international-whql.exe)
3. Turn off Shadowplay in the GeForce Experience
4. Set the nVidia Control Panel to "Prefer Highest Performance" in the Advanced 3D settings
5. Set up the Windows Power Options to "High Performance"
6. Make sure Dolphin is running at its Default settings (by renaming the Dolphin Emulator folder in "My Documents" or by creating a portable.txt in the same folder as Dolphin.exe)
7. In Dolphin set IR to 1x (Internal Resolution)
8. Set Ubershaders to Hybrid
9. Set Graphics Back-end to D3D
10. Set Anti-Aliasing to 1x (or off)
11. Set Sound back-end to CubeB and HLE
12. Turn off Cheats
