Hello, I’m having trouble with a random glitching audio with my Tone2 Pro connected to the USB-C of a Macbook Pro 2020. This occurs with both streaming (through Roon) and local files. The best guess I could make of this issue is a bug with Macs post-2018 with USB 2.0 connections, but I wanted to kn…

Yes! Sorry, forgot to mention that. I updated to the 1.2 version already.

I have not experienced this issue with my 2019 or 2012 MacBook Pros on Catalina (macOS 10.15.7). I wonder if this an O/S version thing. I will say that if you’re using Roon, using a dedicated endpoint device instead of connecting a DAC to Core usually works (and sounds) better anyway. As I type thi…

Hi David! Thank you for the suggestion! I actually did exactly that as an alternative. It was my first RPi assemble and it was fun :slight_smile: Also, more importantly, it is all sounding and functioning great (using RoPieeeXL). Cheers!
