Apologies for the late reply. The message just showed up a couple days 
ago in my email.

If the audio is playing, just without the specific effect on the 
hardware device, it's unlikely to be a problem with buffering or playing 
the audio. A quick look at the code didn't show any glaring issues to 
me, either (the (un)queueing logic looks a bit odd, but if it's not 
causing any dropouts or restarts, it shouldn't be a problem).

It does seem like it's either a driver or hardware problem, especially 
if other effects do work in its place. Unfortunately I don't have an 
X-Fi (let alone a Windows machine) to test things with.
