TVs are getting smarter every day. One of the most advanced features on your LG C1, G1, or Z1 (or others) is the HDMI-CEC that brings a tonne of features to the table. ARC or Audio Return Channel connects your television to the existing audio system using a single high-speed HDMI cable to eliminate the need to have an optical cable installed. ARC sends the sound from apps and other sources from your LG TV to the audio system such as a home theatre or soundbar. Turns out some LG C1, G1, and Z1 users are facing ARC not working issues on their systems. Here’s an account of everything you can do to fix the ARC not working issue on LG TVs mentioned above.

Method #1: Turn on HDMI-CEC
For ARC to work on your system with ease, you must turn on HDMI-CEC, to begin with. Ignore this method if you are already an HDMI-CEC ARC user and the problem with the ARC just started.
Turns out HDMI-CEC is also known as HDMI Control by Sky Q, Samsung calls it Anynet+, similarly, even LG calls it with a different name i.e. Simplink. This means you will have to turn on the function for the ARC to work properly. You will get the HDMI-CEC option on the settings of your TV that enables your system to interact with set-top boxes, soundbars, Blu-ray players, and other devices. Look out for the HDMI control on your LG TV and enable it. This should be fairly easy to do. If it is already enabled and yet you are facing ARC not working issue, follow the next method.

Method #2: Unplug and replug everything
HMDI-CEC takes the order of connection of devices including the TV, Soundbar, and others very seriously. This means if you have not arranged and plugged cables in order, things might not work out. Turns out this method comes in handy if there’s a minor software glitch and all it needs is a reboot to curb and turn on the ARC so please go through it for sure.
- First up, unplug all the cables including the cable powering the LG TV, and wait for a few seconds.
- Plugin the cable to power on the TV.
- Now, plug in any external sound devices including AV amp, soundbar, or others into the HDMI port on your TV first and power ON the corresponding device.
- Next up, connect the set-top box via HDMI and power it ON.
- If you have a Blu-ray or any other media player, it is its turn to be connected and powered ON.
- Now verify if the ARC via HDMI-CEC on your LG C1, G1, or Z1 is working or not.
- This method works both ways if there’s some issue with the proper connection of devices or if there’s any sort of software issue that must have been resolved by now. If not, you are required to follow the next methods unless you find a solution.
My LG OLED 83 C1 reverts to no sound via mute on tv control. I see picture and arc device is active but it maintain mute. I cannot use volume on lg remote and apple. I’ve tried everything. Unplug, replug, factory restart, restart remote, everything….what’s wrong with it. I had to switch to tv + connected wire device to use it.
