Hi all, thank you for keeping me updated on the changes made in 3.5.2. I’ve since pushed that release to my devices, and have one device (the multiroom master Pi 4) working again. The multiroom clients are not yet working. I posted in the original “Raspberry pi 4 - no audio” thread that included the PR that led to 3.5.2, so I’ll link that comment below. Happy to help test as needed - thank you for all you do!
