Headphone control issues

I recently made the switch from a Galaxy to a Nexus 6p, but now this app is having a problem when I try to use the headphone settings. For instance, I have it set up to pause my music when I unplug my headphones and then play again when I plug them back in, but the latter will cause my phone's media volume level to be set to silent. Using the app's option to set a default volume level helps a bit, but random things like turning on wifi sets the media volume back to silent for some reason. Is there anything you can do to help? This used to be the single most helpful app on my phone and now I can't really get any use out of it.

Can you try the latest Beta here. Restart the phone after installing to start fresh.
