Got the chromecast connected to Sony Bravia TV thru HDMI via a splitter but also tried connecting directly, same outcome. Using a HUDL2 tablet to cast a TV episode playing via VLC to TV using Chromecast cast to screen. Picture is perfect but there is no sound on TV, just on the tablet. The TV is also connected to a Samsung Soundbar via HDMI (TV ARC). Also connected to TV is a PS4, a PS3 and a media MKV player, all through a HDMI splitter, which all work fine. Any ideas?
