This is a temporary patch that lowers the default gain for EFX in line with EAX and also reverts AL_EFFECTSLOT_AUXILIARY_SEND_AUTO to false so it does not play on sound channels that it is not triggered for. This is a temporary patch until an actual working 3D sound implementation can be engineered as the original games did not have zone files and therefore no real way to zone audio effects.
