Hi all, I think the headline explain the problem already Using my own mod based on "Next War" with lot of unit artstyle and DCM. The mod is running well but when ingame ( tested singleplayer) i "exit to main menu" or "exit the current game" than BTS crash to desktop. I using a Win 7 machine and have this 2-3 crashs in 10. On my notebook HP Omen 15 with Win 10 it happen 8-9 from 10 times. I only start a new game and repruduce it direcly. If i deactived audio in the civilationIV.ini the problem is not visible!! I have the lastest DirectX 9 installed and also the last Realtek HD Audio driver on both systems. Civ4 BTS is clean installed with the last patch 3.19. It seems something is wrong with the Audio process when i exit to the main menu and so on. Strange is that the problem is not present all the time. It is not related to a single Player Civ or something. If i create a scenaro ( save it with the same conditions), repeat start and exit to main menu i can confirm this problem this way. This makes me crazy..... Does anyone have an idea how to troubleshoot this issue ? Or is maybe an extended audio setting file available to map it better to the Realtek sound chips?
