Dialogue Audio Cut Off Issue

After a few months of having a weird issue with dialogue audio in Mass Effect 2 on the PC, I may have finally found the solution.

The problem reared its head when I switched to Windows 7. While this switch allowed me to finally use digital 5.1 through the on board audio device again – after it had been taken out of Windows XP – it introduced another problem which was particularly noticeable in games with dialogue audio. The issue caused all single audio samples to be cut short by a certain percentage. What this equates to is that when characters had a long line of dialogue, the last few words would often be missing, and the game would go straight to the next line. This wasn’t so noticeable with very short lines, leading me to believe it was some kind of timing issue, like maybe the sound was going marginally too slow. Needless to say, this is kind of annoying in a game with so much d…

I noticed this problem again in Starcraft II, so I had to get to the bottom of it. Fortunately, the latest few responses on the Mass Effect 2 technical support forum – which had not been present when I had this issue before – gave me a clue as to how I could fix my specific issue. My motherboard is an Asus P5K, featuring a bevy of overclocking features, one of which is the N. O. S. setting apparently geared to automatically overclock components according to load. This has a separate PCI setting, which I thought might solve the problem if I scaled it back to default, but no dice there. The solution came when changing the overclock type from N. O. S. to auto. At last! The audio no longer cuts short!

You lose some control over the overclocking this way, but I had only set the N. O. S. to 3% overclock anyway. Perhaps a BIOS update could fix this in the future.
