I just updated to 1.3 using a Mac and it worked perfectly. Unfortunately this release didn’t add the feature I’m really interested in- hardware volume control for the preamp out via USB. When updated, and with the preamp volume control activated, Volumio only provides two options for the Tone 2 Pro- “software” or “none”. “None” mode does exactly what you expect- no software volume control from Volumio. “Software” mode allows volume control, but it is in Volumio, which means that the Tone 2 Pro can’t act as the MQA renderer. What I was really hoping for was to see “hardware” as a volume control option like other DACS where Volumio can control the hardware volume in the DAC so it can still send the full volume stream to the Tone 2 Pro, let the Tone 2 Pro render the MQA stream, and control the new pre-amp volume via USB. Many other DACs provide this feature. @Gouwa Is there any chance of getting this feature in a future firmware release?
