Reasons For Which Your HDMI Arc Audio Drops Out

1. Damaged HDMI cord

You might not notice but an HDMI cord also comes in poor quality. That quickly wears off and gets worse. In that case, you need to replace it with a new one. But make sure that the new one matches with your TV as well as your audio device. I would highly recommend using a 2.1 cord HDMI cord which is of premium quality and durable.

2. Loose Connections

Proven Ways To Get Rid Of Arc Drop out Problem

Believe it or not, the HDMI connections often end up getting loose. Since you connect them manually, you cannot blame the connection itself. It tends to get loose and thus audio keeps cutting out.

3. Outdated Software Version

When you pair up a modern device with an outdated software version, the HDMI arc is unlikely to work because it fails to get compatible with the older software version.

4. Interruption of Wi-Fi devices

Unknowingly but yes, this happens too often. If there is any Wi-Fi device right close to your audio device, then it is more likely to interrupt or even block the signals. Thereby, the HDMI arc fails to operate and the audio starts dropping out.

An Instant Solution That Works In Most Cases

Here is a quick fix solution for your HDMI arc problem. Not just the audio dropout issue but this trick works for other cases as well.

  • Make sure to check the settings of your TV.
  • Go to the HDMI arc option and check whether it is enabled or not.
  • If it shows Disabled, then you gotta enable it.
  • However, if it is already enabled, disable it and re-enable it again.
  • Re-start your TV and check.

Often with the slightest movement, they get loose since they are manually connected. Make sure the HDMI connections to the port of your devices are snug and tight. If they are loose, they wouldn’t function properly, resulting in audio dropout.

3. Check the Settings

  • Go to Settings on your Tv and look for Audio output/toggle. Set it to HDMI arc. 
  • Look for the Digital Sound Out which by default remains in Auto mode. There are usually two options- Auto and Passthrough. If it is set to Auto, move it to Passthrough and vice versa. Sometimes switching these options resolves the HDMI problem.

4. Power Cycling/Troubleshooting

Power cycling all of your devices also help you get rid of this HDMI arc issue. It might get a bit annoying but surprisingly, it works most of the time. Simply turn off your TV, audio device, or media player. Wait for 10-20 seconds and restart them. Resetting the power helps your audio device to understand the settings.
