Ok here it is...
The deck gun when firing sounds muffled, the flack gun is silent, and many explosion sound effects are not heard.
I had a clean (crystal) install of GWX 1.02...all went well with the first patrol. I docked to port and exited the game. Installed CH3cmmdr 2.7 and patched the cfg folder with the contents of GWX102Cfg4SH3Cmdr.zip
Everything else works ok....I don't get it....
