So my situation is a bad one. I currently use Airplay on my Marantz processor in the HT, and AppleTV as well on my second AVR in the living room area. I absolutely love the ability to stream music over the speakers in different areas of the house and the control at my fingertips via the remote app on my Iphone. I say, love, right now it is more hate. Somehow, between my Airplay (and ONLY my airplay) a setting has somehow gotten stuck where when I am using airplay, the volume on my Marantz will only go up to -6 where it stops, not to go any further. I pause airplay and it works fine all over again, or I switch over to my fiance's airplay or a friends using their particular idevice, once again it works fine. The volume limiter only happens on my particular Library/Device.
I have no idea how it happened, but even after a brand new phone, a brand new computer, and resetting all network and AVR's MULTIPLE times, this setting is still affecting my Marantz. It is obviously not an issue with the Marantz as all other airplay devices work fine with it, and play nicely, and when I pause mine it works fine. I am at a total loss here and have NO idea where I could be missing a settings of any sort. Deletion of apps, resetting of phones, etc, etc has got me at my wit's end.
I really hope someone can lead me in a direction I have obviously not managed to find on my own.
