Samsung TV: Fixing Audio Delay Setting Not Saving -... | digitalhomefaults.org

Technical Background:

The Samsung TV's audio processing unit (APU) stores user-configured audio settings, including the digital output audio delay, in non-volatile memory (EEPROM or flash memory). The TV's firmware manages read/write operations to this memory. The digital audio signal (S/PDIF or HDMI ARC) is then processed by the APU based on these settings before being output. The configuration process involves a software interface, signal transmission, memory write operation and a confirmation/acknowledgment signal.

Symptoms:

The 'Digital Output Audio Delay' setting within the Samsung TV's audio menu reverts to a default value (typically 0ms) after the TV is powered off, restarted, or the menu is exited. This occurs despite repeatedly saving the desired delay. No error codes are displayed, either on-screen or within the Samsung SmartThings app.

Possible Causes:

Corrupted firmware or software glitch preventing the setting from being properly written to non-volatile memory.
Insufficient power during the memory write operation, leading to data corruption.
Failure of the non-volatile memory itself (EEPROM or flash memory).
Conflict with other audio settings or connected devices (soundbar, AVR).
Incompatibility with the connected audio device’s input buffer settings.
Intermittent power fluctuations due to aging capacitors in the power supply, more prevalent during Canadian winter brownouts.

Solution:

1

Perform a soft reset: Unplug the TV from the power outlet for at least 60 seconds, then plug it back in.
2

Check for firmware updates: Navigate to Settings > Support > Software Update and check for available updates. Install any pending updates.
3

Reset the audio settings to default: Navigate to Settings > Sound > Expert Settings > Reset Sound. Confirm the reset.
4

Test with different digital audio output formats: Navigate to Settings > Sound > Expert Settings > Digital Output Audio Format and try different settings (PCM, Dolby Digital, DTS).
5

Disconnect all external audio devices (soundbar, AVR) and test the TV's internal speakers. If the setting saves with internal speakers, the issue may be with the external device. Check the external device manual for compatibility settings or firmware updates. Ensure the HDMI cables are certified and meet the required bandwidth for ARC (Audio Return Channel).
6

Perform a factory reset: Navigate to Settings > General > Reset > Factory Reset. Note: This will erase all personal settings and data. Back up any critical data before proceeding.

If the issue persists, contact Samsung support for warranty service. Provide detailed information about the steps you've already taken.

Safety Warning:

Ensure the TV is disconnected from the power outlet before attempting any physical troubleshooting. Do not attempt to open the TV chassis unless you are a qualified technician. Improper handling of electrical components can lead to serious injury or death. Data privacy is a serious consideration. Always use strong passwords to protect your home network. Review the Samsung TV’s privacy settings and adjust them according to your preferences. Be aware that Samsung may collect viewing data.

Prevention:

- Regularly check for and install firmware updates (OTA) to ensure optimal performance and bug fixes. - Use a power surge protector to protect the TV from power fluctuations. - Avoid frequently power cycling the TV (turning it off and on repeatedly in short intervals). - Back up TV settings when possible (some Samsung TVs offer cloud backup).

Expert Tip:

If the audio delay setting reverts after each power cycle, try setting a static IP address for the TV on your home network (via your Bell Giga Hub or Rogers Ignite modem settings). A dynamic IP address change can sometimes trigger a settings reset. This also applies if you are using a VPN on the TV.

Frequently Asked Questions

•Is there a way to back up my TV settings before doing a factory reset?

Some newer Samsung TVs offer a cloud backup feature within the settings menu. Check the TV's user manual for instructions specific to your model. This is the best way to avoid having to re-enter all your credentials.

•My soundbar is connected via HDMI ARC. Could that be causing the problem?

Yes, HDMI ARC issues are common. Ensure your HDMI cable is certified for ARC. Try a different HDMI port on both the TV and soundbar. Also, check your soundbar's settings for any conflicting audio processing options (e.g., Dolby Digital, DTS).

•How do I find the firmware version of my Samsung TV?

Navigate to Settings > Support > About This TV to find the current firmware version installed on your Samsung TV. Compare this version to the latest available on the Samsung website for your model.
