Difference between build 39247040 and build 39247040c?
Hi Terry, the build is specific to the type of device that is running the software. I believe the 39247040c build is for the Sonos hardware, while 39247040 is for controllers. The version number is the same, this is expected and nothing to worry about.



You might even see the build different between players sometimes depending on if specific updates were needed for unique hardware versions.
Many thanks Ryan.
