I think the General protection fault in KERNELBASE.dll was caused by you renaming wrap_oal.dll to OpenAL32.dll, so try changing it back.
I believe the wrap_oal.dll_unloaded error is related to having hardware audio enabled, so try either of the following:
- Disable the "Hardware Audio" setting in the game's sound settings. Note that you won't get surround sound if you do this.
- Use IndirectSound (follow the instructions for Mass Effect), which lets you keep hardware audio on and therefore have surround sound.
See my reply in the "Mass Effect PC (Steam) - General Protection Fault" thread for more details.
