My playbar(1)has stopped working since the TCL TV has updated it’ software.  The optical setting is switched on but the playbar will not recognize the optical connection.  Prior to this upgrade the sytem was working perfectly along with my two Play 1 speakers setup as a home theater system.  How can i correct this problem.   I have been through the system setup again on the Sonos app but the playbar is not seen by the TV.
