The min should always be 1. We have other ways of bumping the number of buffers to 2, like the ASYNC allocation flag which we can set if we are also doing some async scheduling. We could make this an option later. Otherwise, we would also allocate 2 buffers by default between the mixer and the node, which is unnecessary.
