I just got a brand new LS50WII to pair with a half year old Samsung TV through HDMI ARC, Optical and Bluetooth with very disappointing results:
HDMI ARC - once the speaker is connected, they show up in TV’s audio output menu as an option, but once i choose it, the sound will play through LS50 for about 3 seconds and then it drops. If i select a different source on the LS50 then back to TV, it comes back to the menu but the same happens again. I had a Pioneer receiver previously and connected through ARC to the TV with zero issues.
Optical - Can be selected by the TV, but no sound out of LS50 at all.
Bluetooth - there is a 0.5 to 1 second sound delay so not usable.
I changed the TV’s sound output mode to PCM as I found a few posts mentioning that.
Has anyone experienced this or have a suggested solution?
