Just to clarify, it was through a Sonos amp feeding ceiling speakers not a playbar. There was no configuration that we could come up with to get the TV sound through the speakers wth the new driver, unless someone has any other recommendation.
Actually, your dealer and tweeterguy are both correct. Problem lies within a lack of discreet input ( aux ) switching command in new driver. Yes, you can set up your Sonos amp as tweeterguy described it in his post, however the moment you decide to listen to Sonos music while TV is on, " auto " sensing/switching goes out the window. You will not be able to switch back to TV ( using C4 remote ) unless you shut system off first, or use Sonos app to force aux input.
Despite the warnings, I am still using " unofficial " C4 Sonos drivers. I ( want to ) believe that sooner rather than later endorsed driver will have some basic additional functionality - i.e input switching.
