RE CV Sound problem

My sound in RE Cv has a problem
Everytime someone speaks its like theres an echo and sounds like garbage. Its like their speaking underwater.
Although some of the words I can understand,
Most I cant. What seems to be the problem?
Im using latest version of chankast 0.25 and NullDC.
Thanks

It's a normal problem. Sadly you need to wait for the next nullDC version.
