I have a Bush TB342, which works perfectly with TV and DVD. However, when watching something either on Now TV or Chromecast, as soon as I turn on the soundbar, they freeze. I have tested this, and it's 100% repeatable - as soon as the sub is powered up, Now TV or Chromecast simply lock up. Leaving the soundbar off, I get no such interruption. I am on BT Infinity with a Homehub 5, and the signal is good throughout the house. Any ideas on how to fix this?
