iPhone volume control with buttons

As a preface, I’m not sure if this is a bug report or a feature request.

I love the Audirvana player and remote, but I cannot use the volume buttons on my iPhone to control the Audirvana player volume using the remote.

I do have software volume control on and I can control the volume using the slider bar in the remote app. However, this is very cumbersome. Volume control is one of the user interactions that requires the most immediacy. If the volume is suddenly too loud because the there are large dynamic changes within or between songs or between albums, one often needs to change the volume FAST. At present, I have to unlock my iPhone, find the app, press on it to open it, press on the song to access the volume slider, and then slide the volume. This is too many steps.

Many remote apps allow for direct control of the volume via the phone hardware buttons. This would be a valuable feature to add in my opinion.

Thanks for your time and consideration.

There are some good resources for iOS developers on how to accomplish the above:
