UPDATE:
I unplugged all the connections from the telly and left in the sound bar and voilà! it connected through the HDMI ARC
Then I plugged in my PS4 and all the sound went through the soundbar as expected.
I then plugged in my telly and it dropped the connection instantly and the HDMI ARC...
Hi all.
I have a LG 49UH668V telly and a Philips HTL 5140 Soundbar.
When trying to connect them via HDMI ARC I can get all the way to the sound test and no sound comes through (yes, all the settings on the telly and soundbar are correct for HDMI ARC)
I have a brand new HDMI 2.0 cable as well...
