HDMI ARC Issue with LG C9 and how to fix it.

[akhilesh malladi]

hi, Friends,

i have finally fixed the HDMI ARC issue.
Apparently some people also had the same issue and couldnt figure out whats wrong.
After reading through AVSForums, I finally understood that LG had a bug in HDMI operation as well..

The problem happens when your TV is already sending sound through HDMI ARC to a AVR and you try to connect additional sources like dth or blueray player to additional HDMI ports of TV and AVR. Once you add additional sources, you might try to use LG's device connector setting to control the device and this is where HDMI ARC stops working.

Solution:
disconnect all hdmi ports of TV and AVR.
Full reset TV and AVR.
Only Connect HDMI ARC port of TV with HDMI ARC OUT of AVR. Enable ARC feature on both TV and AVR. Open LG TV internal app,
and check if sound is coming properly to AVR.
Now you Connect All additional sources to other HDMI ports of TV and nothing should be connected to AVR.
You may use LG device connector setting to configure the magic remote to control them.

MY current setup of TV:
HDMI 1: Airtel DTH.
HDMI 2: ARC connected to Denon AVR 1500H.
HDMI 3: ACT Television(Using this to play hotstar premium content as LG inbuilt APP is not playing it)

Good news:
LG magic remote can control all 3 devices seamlessly and thats a great ease for customers.
I shall appreciate LG for this.

I just encountered this issue (and your post) but your solution did not fix it for me.

Thanks it works for me. The steps I wish to emphaise is make sure you remove all connectors from the ports. Power off the TV and sound bar, starts off with the ARC connection first.

My soundbar is from Sonos but I faced the same problem describe here.
