Samsung eARC: Fixing 'Audio format not supported' Error... | digitalhomefaults.org

Technical Background:

The Samsung eARC soundbar relies on the HDMI Enhanced Audio Return Channel (eARC) for transmitting high-bandwidth audio signals from a connected TV or source device (e.g., Blu-ray player, streaming device). Successful audio transmission depends on proper HDMI cable connectivity, compatible audio codec support on both the source and soundbar, and correct audio output settings configured on the TV. Power consumption during audio playback fluctuates between 30W and 60W, depending on the audio format and volume level. Wireless communication occurs via 2.4 GHz Wi-Fi for firmware updates (OTA).

Symptoms:

No audio output from the Samsung eARC-enabled device when attempting to play content with specific audio codecs (e.g., Dolby Atmos, DTS:X). Observed error message on the connected display indicating "Audio format not supported". No abnormal LED activity detected on the soundbar itself.

Possible Causes:

Incompatible audio codec: The source device is attempting to output an audio format not supported by the Samsung eARC soundbar.
Incorrect HDMI cable: The HDMI cable is not eARC-compatible or is damaged, preventing proper audio transmission.
TV audio output settings: The TV's audio output settings are not configured to utilize eARC or are set to a conflicting audio format.
Firmware incompatibility: The Samsung eARC soundbar or connected TV is running outdated firmware, leading to codec incompatibility issues.
HDMI port malfunction: The eARC-enabled HDMI port on the TV or soundbar is faulty.
Ground loop interference: Electrical interference causing signal degradation on the HDMI cable, common in older Canadian homes.

Solution:

1

Verify HDMI cable: Ensure a high-speed HDMI cable with Ethernet is used, and it is securely connected to the eARC-designated HDMI port on both the TV and soundbar. Replace the cable if necessary.
2

Check TV audio output settings: Access the TV's audio output settings menu and confirm that HDMI-eARC is selected as the audio output device. Set the audio output format to "Auto" or select a supported format (e.g., Dolby Digital, DTS).
3

Update firmware: Check for and install the latest firmware updates for both the Samsung eARC soundbar and the connected TV. Use the Samsung SmartThings app or the TV's settings menu to initiate firmware updates.
4

Source device audio settings: Confirm the source device (e.g., Blu-ray player, streaming device) is set to output a compatible audio format. Refer to the source device's manual for instructions.
5

Power cycle devices: Disconnect the power cords of the TV, soundbar, and source device for at least 60 seconds. Reconnect the power cords and power on the devices.
6

Factory reset: Perform a factory reset on the Samsung eARC soundbar by pressing and holding the "+ and - volume" buttons simultaneously for 5-7 seconds until "INIT" appears on the display. Then reconfigure the eARC connection.
7

Test with different source: Connect a different eARC-compatible source to isolate potential faulty components.

Safety Warning:

Before disconnecting or reconnecting any cables, ensure all devices are powered off and unplugged from the power outlet to prevent electrical shock. Do not attempt to repair or modify the Samsung eARC soundbar or connected devices yourself. Contact a qualified technician or Samsung authorized service center for assistance. Ensure proper surge protection to mitigate damage from power surges, common during summer thunderstorms in Canada.

Prevention:

- Regularly check for and install firmware updates for all connected devices. - Use high-quality, certified HDMI cables to ensure optimal signal transmission. - Periodically review and adjust audio output settings on the TV and source devices as needed. - Ensure proper grounding of all connected devices to minimize electrical interference. - Inspect HDMI cables for damage or wear and replace them as needed, especially after Canadian winters with frequent power outages.

Expert Tip:

If encountering persistent eARC issues, try disabling HDMI-CEC (Consumer Electronics Control) on all connected devices. While CEC allows for device control via HDMI, it can sometimes interfere with eARC functionality. Alternatively, use the optical output on the TV to bypass eARC functionality for basic audio support.
