Description of Issue
Since a few weeks I have a problem with sync when I group living room and kitchen. Can’t say when that exactly started. There were updates for Roon, Bluesound and Dutch&Dutch.
The group loses sync when the sample rate of the music changes. If I play an album or radio and the sync works, the system does not lose it anymore.
I use Convolution filters for the living room and the kitchen. These were created with Focus Fidelity Filter Designer. I have found that in case of loss of sync, deactivating and reactivating the convolution filter on one of the systems will bring back the sync.
