Hi,
Because this does not look like normal behavior and it is hard to give a general solution, maybe it is best that you share somewhat more information? What kind of clip, format, any editing applied etc? Does this loudness come during preview or after production, or both? Maybe even better to share (a part of) the clip?

This comes after rendering the whole video, and then when i double check everything to see if its correct, the sound get all loud and hurts my ears (My volume is at 60% and it sounds normal until the glitch happens) I render everything so it runs smoothly, but before rendering, it sounds normal (like clearly hear the sounds normally)

Here is some video proof (WARNING: VERY LOUD)

Ok, thanks for the upload. The sound that I hear is very similar to a wrong digital sound format of some kind or a digital sound track that start at (is cut at) the wrong point….
It strikes me that the noise starts right after a cut. What we cannot hear is whether the sound of ALL the parts of the clip (that ends with 4417) is also noisy or not.
I have some questions and suggestions below trying to help you further with this:
- The original clip, without or before PD, as played with another media player, is the original sound okay?
- what is the format of the original, especially the sound?
- did you render for preview or did you produce
- what are the specs you used for rendering/production
- did you try what happens when you insert the original clip into the timeline of a new project, without any editing? If the sound is noisy then too, it may point to a format of the clip that PD has difficulties with?
- assuming that the original is okay, maybe try to convert the original clip (with HandBrake or the like) to the same format as the example you uploaded H.264 AVC and audio format AAC but with (much) higher bit rate then uploaded? And use that to see what happens in a new project without editing of the timeline, and (of that plays okay), with some of the intended editing?
- and if all other fails, it may also be your system, but I assume that your systems works fine and non of the clips give weird noises outside PD? In case of doubt you might upload the DXDiag file so that we can check?
and let us know what you find?
If this not bring you further maybe download a bit of the original file a few seconds from the point the noise starts in your uploaded file.
Sorry, this this is all I can do at this moment. Maybe other have more suggestions or a solution?

A sample of the original and not the produced clip attached here will be useful for other users to test out on their systems. Use Mediainfo Online on the original clip that will have the problem after producing in PD20 and then download the mediainfo report as text. Attach it to your next reply.

It is possible that the original is a recorded gameplay video. If it is then which recorder or capture was used…

The Original video (unedited) is normal when played on my Windows Media Player playing on Windows 11 OS
The video is a MP4 type format, the bit rate of the audio is 97kbps and the audio sample rate is 44.100 kHz
The Edited video was not produced, it was render for preview so i can make the edits much more smoother to view while editing
(I dont really know how to see my specs for rendering video projects)
Here is the unedited original video down below (also sorry for the notifications in the video)

Thank you for supplying the original clip with the issue.

I have tested the original clip in my system and have no problems in making 5 cuts, rearranging them, playing them, render preview, removing segments, and it still plays properly in PD365. The MediaInfo indicates that the audio is variable bit rate from 96 to 194 kb/s. Variable bit rate in the audio has caused problems in the past especially with the newer versions of PD. I have converted the variable bit rate mp3 in my collections to constant bit rate before using them in PD starting with PD17 through PD365 using Audacity with FFmpeg.

I believe that Warry’s suggestion of converting the original mp4 files with that variable bit audio to a constant bit rate of 96 kbps using HandBrake should fix the issue before you place the original clip on the timeline. This is the easiest and best conversion.
