The sounds in my install are the same. But since i have now had to reinstall GWX3 as there is a problem at the start of the war on mine where i keep getting the message over the radio Twice! every minute, that my base has changed to kiel it could well be i just had a bad install and the sound files got corrupted as well.
Certainly not making a complaint about it. after all when i first loaded up GWX3 i was stunned at all the changes made to the game graphically not to mention all the other hard work that has gone into making the game more realistic. Phenominal work from the GWX team.
I now have PT's sound mod as well so if my re-install works ok then the sounds are not going to be a problem.
