How do I fix headphones that stop working on a Vizio TV eARC HDMI converter after power cycle?
Answer
This usually means the eARC handshake is not recovering cleanly. Plug the converter only into the ARC/eARC HDMI port, try standard ARC with eARC off, then power-cycle the TV and converter together.
Before you start: stop right away if…
- Unplug from the wall outlet carefully and keep liquids away from HDMI ports and converters.
Follow these steps
Confirm the ARC or eARC HDMI port
Plug the converter only into the HDMI port labeled ARC or eARC/ARC. Do not use a non-ARC HDMI input for the converter.
You should see: The converter is on the correct ARC-capable port.
Turn eARC off and test standard ARC
On the Vizio TV, open audio or HDMI settings and turn eARC Off so the TV uses standard ARC. Keep the converter connected and test headphone audio.
You should see: Headphones play TV sound using ARC without needing eARC.
Power off the TV and converter
Turn off the TV and turn off or unplug the converter’s power supply if it has one. Leave both off before the next step.
You should see: Neither the TV nor the converter is actively outputting audio.
Unplug both from power for 60 seconds
Unplug the TV and the converter from the wall for a full 60 seconds, then plug the converter back in first if it has external power, reconnect HDMI, plug the TV back in, and turn the TV on.
You should see: After reboot, headphone audio works again from the converter.
Retest a normal off/on cycle
With eARC still Off, turn the TV off and back on the normal way. Check whether headphones recover without another wall unplug.
You should see: Audio returns after a regular power cycle, or you know eARC must stay off for stability.
Power-cycle the full audio chain if it still fails
Turn off the TV, converter, and anything fed by the converter, unplug them together, wait 60 seconds, then restore power in this order: converter, TV, then headphones or amp.
You should see: The HDMI audio path renegotiates cleanly after a coordinated power cycle.

Extra tips
What to look for: HDMI port labeled ARC or eARC/ARC, Vizio audio settings for eARC, and whether headphones recover only after a wall-power unplug.
Before you change anything: Note which HDMI port the converter uses and where headphones connect from the converter. Write down current TV audio output settings before changing eARC. Leave enough clear space to unplug the TV and converter safely. Never share account passwords if any streaming sign-in prompts appear.
