I've had an LG Smart TV for a while, and recently, I've acquired a Samsung soundbar and subwoofer system. I've tried endlessly to connect these two, to no avail.
TV MODEL: 55LF6090-UB
SOUNDBAR MODEL: HW-F450/ZA
I don't have an optical cable, so I'm trying to use the HDMI ARC. I know it's connected because my TV can sense that HDMI is connected, and the HDMI is plugged into HDMI1, in since it has ARC support. And yet, I just can't get it to work. If anyone can help me figure this out, thank you in advance!
ARC usually has to be turned on in the TV menu.
You may also have to turn the TV speakers off and turn CEC (anynet) on.
You may have to configure the soundbar too. Check the manuals for specific details.
You also need an HDMI cable that supports ARC which a really old one may not.
