Disgaea 2: Dark Hero Days

[Derpamon]

I'm having the same problem as Quizmaster, but having the latest revision doesn't fix it for me.

During cutscenes at seemingly random points, and sometimes just every other voice clip, the voices for the characters will cut out completely. This is seriously bugging me and I've gone through all the settings trying to fix it. If someone has a solution I'd be happy to hear it.

My Computer:
Alienware17 Laptop

My Settings:
Running in OpenGL
Buffered Rendering
Simulate Block Transfer (On)
Frameskipping (Off)
Post-Processing Shader (Natural Colors)
Rendering Resolution (3x)
Mipmapping (On)
Hardware Transform (On)
Software Skinning (On)
Vertex Cache (On)
Lazy Texture Caching (Off)
Retain Changed Textures (Off)
Disable Slower Effects (Off)
No Texture Filtering
No Hacks

Audio:
Backend: WASAPI
Latency: Medium
No Sound Hack

System:
Fast Memory (Off)
Multithreaded (Off)
I/O Timing Method (Fast)
Force Real Clock Sync (Off)
PSP CPU Clock (Auto)
Rewind Snapshot Freq. (0)
PSP Model (PSP-2000/3000)

Any possible help is very appreciated!
