My 55C9 came in yesterday, and I've had NO luck getting the TV Apps (Netflix, Amazon, etc) to send audio back to my Denon AVRX4300H.
I'll explain how I have everything hooked up and I ask that you guys tell me if this is common, if I need to switch something, or what I need to do.
I have my PS4 and cable box (Spectrum) connected to my Denon. From there I have a single HDMI cable going to the TV's INPUT 2 (Labeled ARC).
On the TV, should I assign the INPUT 2 as the Cable box or the AVR box? I think I've done both and I think it's set to the Cable Box right now. Regardless, neither way sent Netflix Audio back to the Denon. it just keeps sending the Cable box audio to the Denon, regardless if the Netflix App is open.
I also went to the Denon settings and turned on ARC.
What else am I'm missing?
I truly apologize if this is common and already answered. I couldn't find anything.
Settings for connecting the Denon X3400H and LG C9 TV
First, you will need to use High Speed HDMI cables; one cable for each device. If you use "active" cables, be sure to have the "TV" or "Display" end connected to the TV. Connect the cable from your TV to the X3400H, to the C9's HDMI2 port. That is for eARC. Connect the other end to the Denon's HDMI port: AUX2. You will select TV Audio on your remote, but use AUX2 as your port.
Second, connect one of the other cables into the C9's HDMI1 port, and the third cable into the HDMI3 port. All three ports are in a line.
Third, connect the other end of the HDMI3 cable to the PS4,
Fourth, connect the other end of the HDMI1 cable to your Spectrum box.
On your X3400H, go to Settings and set the following:
Picture Mode Off
HDMI Setup Auto(Dual)
Pass Through Source AUX2
RC Source Select Source Select Only
HDMI Control On
(eARC is automatically "On" when HDMI Control is "ON")
TV Audio Switching On
Power Off Control Off
Power Savings Off
Smart Menu On
HDMIVideo Output Auto(Dual)
Video Mode Movie
Video Conversion On
i/p Scaler Off
4K Signal Format Enhanced
Input Assign AUX2 2
Source Level 0db
On your C9, go to:
1. All Settings -> Connection -> HDMI Device Settings -> Auto Device Detection "ON"
2. All Settings -> Connection -> HDMI Device Settings -> Simplelink (HDMI-CEC) "ON"
3. All Settings -> Connection -> HDMI Device Settings -> Auto Power Sync "ON"
4. All Settings -> Connection -> Device Connector -- follow the prompts. Run the Home Theater (Denon) first.
4a. If the C9 returns that your Denon is a sound bar, go back to step 1. (Auto Device Detection) and turn it "OFF". When you reach Step 4, Click the "Reset Device" button under the LG's Device Connector to clear its memory. Re-run step 4. Re-set Auto Device Detection to "ON".
4b. If the C9 returns that your Denon is an AVR, using eARC from port HDMI2, go to step 5.
4c. If you clicked on “Reset Device”, go again to All Settings -> Connection -> HDMI Device Settings -> and set Auto Device Detection to "ON", then go to step 5.
5. Continue to Connect your Set-Top Box and Game Console by following the prompts.
Give it all a try. Best wishes.
