It appears that something has gone wrong with the volume control in Roon. If you restart your computer, does the volume still show the large negative number in the volume widget?
(A) restart Mac with already attached DAC: same
(B) restart Mac without DAC attached later then launch roon.app: same
In both case I can see the high negativ number, without a change to change it.
(C.) Attach the DAC to a raspberry with roopie Image: it works fine.
Thank you for the report. I have filled a ticket with the QA team for further analysis. I will be sure to update you once they have had a chance to investigate this behavior.
In the meantime could you try:
A) Going to the “Device Setup” screen, clicking the “Load Defaults” button, and then clicking “Save”.
B) Reopen “Device Setup” and set the Volume Control to “DSP Volume” then clicking “Save”.
