NOTE: Sound Driver is RTKVHD64 (Realtek HD Audio), 18/10/2011. I'll try and update it today, and see if that helps.
I'm getting computer voice/sound issues with this mod - it sounds like the first 0.5 second is taken from something else, and the 'proper' sound lasts ~1-2 seconds with normal target identify (e.g: Argon One, Terracorp, etc), and menu ship descriptions (such as the description for the discoverer) last ~6 seconds. Weapons effects seem to work normally.
If I run it with "Ignore last setting and use default" the sound problem doesn't crop up, so it has to be a mixup between the Australian game and this mod (v3.5 & v3.5 Alt seems to have a similar issue; it and the EU one may have more differences than previously thought). This occurs with either the normal or uncompressed 0144.dat file as well (renaming the .dat to wma, then converting to .wav, and renaming back to .dat).
If it helps, in the Simulation, Pilot Licence Test, Combat Test 1, the first sentence of dialogue goes "*Forge*. [Not normally part of the sentence] Welcome to the Argon Space Academy... [sentence runs normally] participate in level 2 simulations. *Good Luck*" ["Good Luck" is cut off]
Additionally, if I die, a CTD occurs (which also doesn't occur with the 'use default' setting).
Docking, non lethal crashes and station interaction (purchasing/selling) are fine.
OS: Win7 Professional, Service Pack 1 (64 Bit, obviously).
CPU/RAM: Core i5 3550, 8gb RAM.
Drivers: Unsure, but they must be some of the most recent (this computer was only made 3 months ago), and the windows automatic updater says they are all up to date (except the Nvidia GPU, which has been updated).
X2 Version: Australian 2 CD (Installed 1.0.0->1.2 Aus->1.4 Aus->NoCD->1.5-> AL Patch-> Bonus Plugin 1.04.01), which I then manually moved the FL4.0.4 files to their folders.
I also tested without the v1.5 patch (so it was installed 1.0.0->1.2 Aus->1.4 Aus->NoCD-> AL -> Bonus Plugin-> FL4.0.4).
