Welcome to TresCom!

Sadly there is not a video that shows how to install any of the patches. I don't think I've heard about this issue before. Usually people had issues with no audio at all instead. It could be that the base game is not that compatible with modern systems.
Instead of the quickload patch you could use the cheat: "Hold CTRL+Shirt+Q+W and then release W" at the main menu. Load "JR" and see if you have the same issue.
The patch I would otherwise recommend is the CE patch:
viewtopic.php?f=6&t=10674Download "tpass-ce_v107e.zip" from the first post.
Open or extract the archive anywhere you want.
Open "contrib.zip" and put "D3DX9_43.dll" in the same folder where you've installed the game. (Recommended to install the game outside of "Program Files" in modern systems due to privilege issues or run it as admin.)
Open "tpass-ce.zip". Put "tpassp6.exe" in the same folder where you've installed the game.
Go into the "doc" folder and put "tpass.ini" in the same folder where you've installed the game.
Go into the "configs" folder and pick one of the .INI files and rename it to "trespasser.ini" and put it in that installation folder. I would go with "trespasser_dx9.ini" at first depending on your system.
Download OpenAL:
https://www.openal.org/downloads/oalinst.zip and install that as CE uses it to enhance some of the audio.
This should be it. And hopefully you should be able to run the game properly.
