I don't see anything in there that would cause your microphone to actually mute or change its input volume, but you are using an Amulet remote which is frequently switching VC to off mode. Are you sure the microphone is actually being muted? One thing you can try is to use actions to unmute and set the mic volume levels whenever you want to use this mic instead of the Amulet.
It is hard without seeing it in action. For example, you also have a bunch of commands that use mouse emulation. In theory they could be muting your microphone, although it seems pretty unlikely. Or something else similar could be happening that is hard to see in the log.
