Just figured out and guess read yesterday somewhere
that if you play new las vegas in WINDOW MODE then all works fine for the moment even in high settings.. :foodndrink:
When you start, go to options and choose option window mode in the left lower corner.
Had the problem as described here from the fist second on. that voices, dialogs, gun sound, etc. was not hearable or after pressing escape it all came,...
This problem with the sound ruined lots of my weekend.
Did upgrading , reinstalling of drivers, settings...but looks like its just a program error of New Vegas. :banghead:
I am playing on XP, 4GB, old AMD 3.2, 9800GT, etc.
Hopefully they do an acceptable patch on this game.
Shame on them, even since all was working fine on the similar looking Fallout 3.
(Sorry wrong forum. should be in New Vegas forum..)
