Can't get surround sound with HDTV antenna connected to TV

10,983 1,851 December 25, 2019 at 06:59 PM
I have an LG OLED TV with HDMI port that says ARC
I have a Denon 4400 with an HDMI port that says ARC
My HDMI cable is connected to these ports. My TV is seeing the antenna on the screen and I set the receiver to TV Audio but there is no sound

I went into the settings of the receiver (Video > HDMI Setup > HDMI Control = ON
under that setting it shows as ARC being ON

I went into the TV settings (Sound > Sound Out) and put a check mark next to Audio Out (Optical/HDMI ARC)
Digital sound Out has two options... Auto or PCM...but neither work

So what am I missing? My other sources play through the receiver just fine (Apple TV, HTPC, blu-ray player) but I've never been able to get the receiver to play sound from an antenna as the source.

Are you sure the antenna is broadcasting sound in surround sound? I don't think most OTA stations do. I know my receiver can emulate surround sound from a stereo source but your equipment may not have that capability.

Just want to confirm. The sound works fine from an Apple TV connected to your tv using ARC, or the Apple TV is connected to the receiver?

Is it a decent quality/newer HDMI cable? Not all cables work with ARC.

I think most tv's won't pass audio from the tuner via ARC. You can get audio from the tuner via S/PDIF, but iirc many tv's only pass pcm stereo. If you look at the manual, it may actually spell this out.

Yes all other sources play sound through the receiver just fine. They are all connected to the receiver.

I don't necessarily require "surround" sound, but I would like to use my external speakers instead of my TV speakers. I currently only have a 3.1 setup anyway.

Plus I always thought prime time shows and sports have had surround sound for a while. I remember way back when shows used to have a splash at the beginning saying 5.1 surround sound.

How do you know if the cable can handle ARC? My particular cable says it has ethernet (which I've never heard of HDMI being used for internet).

Try connecting the Apple TV directly to the TV and see if it will pass through audio over ARC. At least you'll be able to tell if it's an issue with the connection between the two or if your tv just doesn't pass sound from a tuner source. Any HDMI cable which supports ethernet should support ARC.

IMO ARC is always a little finicky, just get an optical cable and connect that from the TV to the receiver if you can, it's much more stable.
