This is my first post to this Forum. I've been a very happy user of a microRendu since I purchased it last December (2018). I use it with a Mytek Brooklyn DAC, and the microRendu is attached to it via a hard USB connector. I use a Mac mini running macOS High Sierra, and I'm using Audirvana version 3.2.15 (the latest as of this writing).
The goal in my settings is to avoid any Audirvana software control of the DAC that might degrade the sound, and on the Mytek, I have its volume control disabled so the only thing controlling the volume is my preamp. In Audirvana, I have chosen "DAC Only" setting for the Audio Volume setting. I use the microRendu in MDP/DNLA mode which has no volume setting options.
Until a few days ago, all this seemed to work fine--but suddenly, even after restarting the microRendu, Audirvana and even the Mac, now the volume is controlled by the Audirvana software. Worse, the sound appears distorted a times, even if I back off the volume control within the software. Of course, I DON'T want any software control of the volume, but I can't seem to get the system back to the wya it was operating a week ago no matter what I try.
Does anyone have any ideas of what may be going on or how I can fix this issue?
