I should be able to adjust volume on ROON by setting the OpticalRendu’s ROON END POINT settings to DEVICE VOLUME from FIXED.
I will report back here if it works. There is some concern by 1 of the Sonore principles that this may not work. Though 2 other Sonore folks tell me it will work.
@yyzsantabarbara by chance did setting the OR as a Roon End Point with device volume instead of fixed volume work? Seemed like Sonore wasn’t entirely definitive at the time of this writing in 2022.
