I want to play NWN 1 again but I try to find a good resolution but right now none is working and the sound in the cutscenes are nonexistent
any tips to do resolve this?

What do you mean saying that "no resolution is working"?

I try every resolution option but it doesn't change anything

Were you able to sort things out or do you still need help?

still nothing.
still looking for solution

Try to run the game as administrator, maybe that'll help. Also, post your PC config here, maybe there's something wrong with that.
As of sound: I too have this problem (clunky sound / no sound) during the game, and the only solution that worked for me was to start
NWN Toolset (nwtoolset.exe from your game directory) and check the option Start normally then close it, and start the game as administrator.

Hope this helps.
