Reset Sony TV to Factory Settings

If you’ve tried the previous steps and are still experiencing Audio Return Channel issues, performing a factory reset on your Sony TV might help resolve persistent problems. This should be considered a last resort as it will erase all your personalized settings.

Backup Important Data

Before proceeding with a factory reset, make sure to backup any important data, such as app login information, network settings, and personalized picture or sound settings. You’ll need to reconfigure these after the reset.

Access Reset Option

Navigate to the “Settings” menu on your Sony TV. Look for options like “Storage & Reset,” “System,” or “About.” The exact location may vary depending on your TV model. Find and select the option for “Factory Data Reset” or “Reset to Factory Settings.”

Confirm and Wait

You’ll be prompted to confirm the reset action. Be aware that this will erase all data and return the TV to its original factory state. Once confirmed, the TV will begin the reset process, which may take several minutes to complete. Do not turn off the TV during this process.

Adjust TV Sound Settings

Incorrect sound settings on your Sony TV can sometimes interfere with proper Audio Return Channel functionality. Adjusting these settings can often resolve audio-related issues and improve your ARC experience.

Access Sound Settings

Navigate to the “Settings” menu on your Sony TV and locate the “Sound” or “Audio” options. The exact path may vary depending on your TV model, but it’s typically found under the main settings menu.

Select Correct Audio Output

In the sound settings, look for an option called “Audio Output” or “Speakers.” Ensure that this is set to “Audio System” or “External Audio System” rather than “TV Speakers.” This tells the TV to send audio through the HDMI Audio Return Channel connection.

Adjust Digital Audio Out

Look for a setting called “Digital Audio Out” or “Digital Audio Output.” Set this to “Auto” or “PCM” if you’re experiencing audio syncing issues or if your audio device doesn’t support all audio formats.
