The version of Pulse that's installed now is 7.0-5.1. The behavior: If one of the many games in my Steam list is not playing any audio, one of the first things I do is try to run it with padsp. If the executable is 64-bit, then it runs with audio. If the executable is 32-bit, I might as well give up, because padsp does nothing (except sometimes prevent it from running at all).
