If a game uses a sound buffer of N samples, and plays back with frequency M Hertz, then the sound delay D in seconds will be given by
D = N / M. So if the game doesn't scale buffersize by the mixer frequency (and looking at the code, i don't think it does), halving the MixRate will double the sound delay. I expect that changing this

multivc.h:#define MixBufferSize 256

to something liike

multivc.h:#define MixBufferSize (int)(256 * MixRate / 44100)

would solve the problem.
