using Linux Mint 19 operating system
how can I run Psychnauts, because it wont start, tried running from desktop shortcut but nothing, then tried running from game directory start.sh and nothing, so I tried running from terminal and it says:

~/GOG Games/Psychnauts$ ./start.sh
Running Psychnauts
./start.sh: line 19: ./Psychnauts: No such file or directory

I was instructed by another user to install 32bit binaries support by typing the following in to the terminal:

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libc6:i386

after that the game still wont launch but at least i get something different.
Now, wen the game is started from terminal now I get I get the following:

~/GOG Games/Psychonauts$ ./start.sh

and this is where I am lost, need help please

I had already installed support for 32bit binaries.

I followed the suggestions on this forum:
https://www.gog.com/forum/psychonauts/how_to_start_game_in_linux_mint_183/page1

got the game to work by typing this on the terminal

sudo apt-get install InsertLibraryNameHere

did that for all these libraries:

libc6:i386
libasound2:i386
libasound2-data:i386
libasound2-plugins:i386
libstdc++6:i386
libx11-6:i386
libxcb1:i386
libxcursor1:i386
libxrandr2:i386
libglu1:i386

after all of that the game worked but the sound was terrible, every time there is any sound or music or voice, there is this very loud static noise at the same time always and its just terrible.

found another GOG user who made a forum post regarding sound problems with the game, here is the link.

https://www.gog.com/forum/psychonauts/linux_version_sound_problem_resolution/page1

only problem now is that I don't know how to "substitute the shipped OpenAL library file with the current one" like he suggested to fix the sound problem. He makes it sound so easy but i have no idea how to do that on Linux.
