Pick a stream at random according to the probability weights chosen for each stream, but avoid playing the same stream twice in a row whenever possible. If only 1 sound is present in the pool, the same sound will always play, effectively allowing repeats to occur.

Pick a stream at random according to the probability weights chosen for each stream. If only 1 sound is present in the pool, the same sound will always play.
