I was wrong about this. My apologies to my fellow Roonies and to Matrix Audio.
Over the past two days, I had a chance to do more tests with different inputs available on mini-i pro 3 and the issue was with my gear and how I was trying to use it. Essentially, I was expecting to hear sound when the volume on the mini was at -50.0dB and I still didn’t get sound when increasing the volume to -40dB and I stopped there and went back to fixed output. If I had gone up to -35dB or higher, I would have begun to hear the audio as expected.

Below is my original post from 8/24. The finding below is false as I’ve explained above.
I updated the firmware on my mini-i pro 3 around a hour ago. The unit found that the latest firmware available was version D013B8.
After upgrading to this version, my mini-i pro wouldn’t output any audio on the RCA line-out when the attenuated volume control setting was enabled. The volume value displayed on Roon matched the volume set on the mini-i. So Roon was able to communicate with the unit and show the progress of the streaming track, but there was no audio.
As part of the troubleshooting process, I set the volume control to fixed and I was able to get audio again. Not sure if this is some peculiarity with my setup or hardware version V1414, but since what this firmware broke is such a crucial feature for some people. I wanted to get this warning posted on this forum.
