First, I am loving my Model 976, it's a vast improvement over my previous Marantz in audio quality. One issue that I am running into is the FireTV Cube that I bought to serve as my streaming device is sending content at much lower volume than any other device I have tested including my disc player, TV (via arc), and nvidia shield. This is about a 30db difference, so it is more than a minor adjustment. Has anyone else run into this issue, and if so, were you able to resolve it? I am hopeful that there is a setting or configuration which I have overlooked on one device or the other.

Amazon has released updates that allegedly address some functional problem for the "automatic volume leveling". If you have that update applied and the problem persists I recommend contacting support for FireTV -- https://www.amazon.com/gp/help/customer/contact-us?ie=UTF8&

Did those updates actually fix the issue? Did someone test this?
