I am using an Oppo UDP-203 via ethernet connection, running a digital coax cable into an integrated amp.
Description Of Issue
When I use “Device Volume” as a setting for the Oppo, my ability to change volume level in the iPhone app is greyed out. At start of playback, the music is incredibly loud, likely above 75Db reference level, no matter what the volume is set to on the amp. I am afraid of damaging my speakers. I had to change to “fixed volume” with a max cap on volume to fix this.
However, I have another wireless speaker for which I use Roon via Airplay. There, I use device volume with no issue and am able to control volume via the app or via the speakers volume controls itself. So, this begs the question for me of what is the difference between device volume and fixed volume? If I want to control volume on my amp, not via Roon, which setting should I use?
