Playbase and speakers all working fine on the TV and volume can be controlled via the TV remote. However since the last upgrade all the Android Apps (phone, tablet) can't "find" my Sonos. When you start the App .... Searching for Sonos on WiFI, Hang on ... Can't connect. Unplug router, reinstall App, ... Nada. As I said the playbase and the remote speakers all work fine off the TV, I just can't play music from my phone or use the apps advanced sound features like speech enhancement, nighttime etc.
