Hi All,
Thank you for the reports, we were able to reproduce this behavior and have filled a ticket with the development team.
While we wait for a fix, there is a workaround that will allow you to keep the MQA Core Decoder enabled across reboots of the Roon Core process.
A. Open the Device Setup screen for the zone.
B. Set the “MQA Capabilities” setting to “Renderer Only”.
C. Set the “Enable MQA Core Decoder” setting to “Yes”.
D. Click Save.
This will enable the MQA Core Decoder automatically while allowing the configuration to persist between restarts of the Roon Core process.
