Qt has a leftover from the old SPU2-X values which is 3000 ms (3 seconds) latency meaning that if an user sets it to the max it will do something like this: Videoframe ~150 / 180 happens and it makes the first sound after 3 seconds for the first videoframe which is far too long. Also changed 1% speed as it messed with the GSdump player and too stuttery to be usable in other usecases.
