Currently, I’m testing another way to workaround the issues and it seems to be working. It’s been some days without issue (crossing fingers).
For starters, when I’ve upgraded to Roon v2.0, the erratic behavior was still present (and even worse). It was really frustrating and I was so desperate I started trying other cables too (again).
And then I thought, why not use a USB-C adapter (or a USB-C to USB-B cable).
So, I used a spare USB-A to USB-C adapter to attach the DAC to a USB Type C port at my docking station.
Now, almost a week later I haven’t got any issues with MQA playback!
It makes a bit sense that the issue was actually the support of Macbook for USB-A ports but as I said it’s too soon to say. For now, I’m happy to enjoy my music lossless and… MQA, whatever Roon picks for me
