AutoVoice Starting autovoice with the screen off? Ok google unreliable

I've turned on the "any screen" and "bluetooth hands free" google now settings, but they rarely work. I've followed these instructions, and i used this slice of the FAQ without success:

"When I use the AutoVoice Recognize action with the Bluetooth Headset option enabled, I can’t get any voice command to be recognized!
Try starting “AutoVoice Recognize” without the Bluetooth Headset option enabled and in the same Task, right after, enable Bluetooth sound redirection with the “AutoVoice Ctrl BT” action. That is known to work in some cases."

Are the instructions out of date, or do i need to use a additional app? What am i missing?
