Alright. So first, I’m running the most recent version of shotcut.
The video mode is HD 1080p 60fps.
I’m using the DirectX (ANGLE) display method.
Using windows 8.1, version 6.3.9600 build 9600. 64 bit.
My processor is a Intel® Core™ i5-4590 CPU @ 3.30GHz 3.30GHz.
I have 8 GB of installed physical memory (RAM).
I feel like a screenshot wouldn’t help an audio problem so I won’t include it.
The extension type for my source clips I used was mp4. The codec for my video appears to be H.246 / AVC / MPEG-4 part 10
The resolution is 1650x1050.
Framerate was 60fps.
I don’t know how to check bitrate, but the audio codec was AAC.
I don’t think export presets matter, but I just used default. I didn’t go into the advanced changer, and I do have hardware encoder checked.
As for the steps, all I have to do is open my clip into shotcut and the audio crackling appears. I do want to fix this so ill try to respond quickly if and when you respond.
If you only have one hard drive, and if that one hard drive is a physical HDD, you’re going to get a slower performance than if you have a SSD. If you’re drawing your source file or editing off of a USB drive/thumb drive, you’re limiting yourself even further in speed.
If you’ve applied filters, done transitions, and getting audio issues during preview, that’s normal to some degree. You haven’t stated under which conditions you’re experiencing issues.
Have you tried using the 32 bit version?
You can install multiple versions of Shotcut, just name the Shotcut folder when you are installing it.
I’m suspecting that you’re experiencing hardware limitations at this point, and I may not be able to recreate the issues you’re having. I have 32gb on my system and I run with 2 SSD’s One for the operating system and one for recording/editing.
One other thing to check for is make sure your source video audio is in stereo.
And it matches up with your Settings - Audio Channels
So, first off, my monitor only supports 1650x1050 which is why I have my clips in that way. I am used to applying filters and having the audio be a little slower, but this is something new that came after I updated shotcut to the current version. I currently am using the 32 bit version, and I will try to install a previous version of shotcut to see if it also happens on there too. Everything is in stereo and such.
I went back to the previous version. There is no audio problems that I am not used to. I think it had something to do with the update.
As stated, installed latest version and audio was crackly. To recreate, drag a .MTS video in and play.
I uninstalled current version and went back to previous version and problem went away. Previous version = 19.08.16. QT = 5.9.7

Are you testing the export in Shotcut? If so, do not do that. Because of this bug, you need to test in a known good player for you such as Windows player or VLC.
Both of you mentioned going back to version 19.08, but do you know if the problem appeared first in 19.09, 19.10, or 19.12 releases?
See this related post
In version 19.09 we upgraded the FFmpeg codec library, which would affect both preview and export. In version 19.12, we upgraded the SDL2 audio library, which would affect only preview.
