Beast, you say it's the "sample rates" how do we tweak this or make sure it's the same as stock?

I use Wavepad to edit the OGG and WAV files. Typically a voice sample rate should be 44100 Mono. Some other sound samples may be stereo but I wouldn't recommend it as the game handles left/right frwd/back channel control depending on you sound settings and sound hardware.
If you try saving at a higher quality sample rate you will have problems.
if you are using 44100 mono and still having problems, it may what Jan point out, faulty hardware or drivers.
