Summary: Defense Grid, the Awakening: Fails to load, X3DAudio1_4.dll Product: Wine Version: 1.1.11 Platform: PC-x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: directx-dsound AssignedTo: wine-bugs@winehq.org ReportedBy: wolfwings@gmail.com
Trying to load the game complains about the dll X3DAudio1_4.dll being missing. Loading that dll into the game directory manually allows it to get as far as changing the screen resolution before dropping a game-propietary crash-dump into the game directory.
Contacting the developer, they were helpful enough to stage that the crash was occuring in Microsoft's DirectX audio engine (the X3DAudio1_4.dll file) from the crash-dumps the game itself generated, so we're basically back at square one in that regard.
