With current RAM sizes and soundcard speeds the only suitable DMA buffer
size is 64k. For this reason having this option just cause confusion.
Users tend to spend hours in optimizing the buffer size in cases where it
doesn't make any difference.

The delay with Quake is caused by a bug in the driver or in Quake.
Actually I think it may be caused by a bug in earlier driver versions
which was compensated by adding a "bug" to Quake. I will try to find a
solution to this problem.
