Samsung Earbuds HDMI Not Working
Struggling to get audio through your Samsung Galaxy Buds when using HDMI inputs or TV eARC connections? Learn how to fix HDMI audio routing, PCM downmixing, and Bluetooth handshaking issues.
Symptoms
- No sound through Samsung Galaxy Buds when switching to HDMI inputs (gaming consoles, streaming boxes)
- Audio works on native Samsung TV apps but mutes completely on HDMI sources
- Severe lip-sync delay or lag between HDMI video and Galaxy Buds audio
- Earbuds frequently disconnect when changing HDMI source ports on the TV
- Distorted static or popping sounds when receiving multichannel HDMI audio
- Samsung TV Bluetooth menu shows Galaxy Buds connected but reports no audio stream
Quick troubleshooting
Step 1
Force TV HDMI Audio Output to PCM
Navigate to your TV sound settings, select Expert Settings, and set the HDMI Audio Input Format from Auto or Bitstream to PCM. Samsung Galaxy Buds cannot process raw 5.1 or 7.1 multichannel surround streams directly over Bluetooth. Switching to PCM forces the TV or HDMI source to downmix audio into a 2-channel stereo signal compatible with wireless earbuds.
Step 2
Toggle Anynet+ (HDMI-CEC) and Power Cycle
Go to the TV External Device Manager settings and toggle Anynet+ (HDMI-CEC) off and back on. Turn off the TV, unplug the HDMI cable from your source device for 30 seconds, and reconnect it. This resets the HDMI handshake and clears audio bus conflicts between the HDMI port and the internal Bluetooth transmitter.
Step 3
Disable eARC Mode in TV Sound Settings
In your TV audio menu, set eARC Mode to Off while listening with Galaxy Buds. eARC is designed to bypass internal TV audio processing to send uncompressed audio to soundbars, which often prevents internal Bluetooth re-encoding for connected wireless earbuds.
Step 4
Unpair and Re-bind Galaxy Buds to TV
Remove your Samsung earbuds from the TV Bluetooth device list. Place both earbuds into their charging case, hold both touch pads for 7 seconds until the LED flashes red and green to enter pairing mode, and reconnect them directly through the TV audio menu while the HDMI input is actively playing.
Step 5
Reset Earbud Firmware in Galaxy Wearable App
Connect your Galaxy Buds to your Android or iOS smartphone and open the Samsung Galaxy Wearable app. Check for pending firmware updates under Earbuds Settings, then perform a Reset to clear corrupted Bluetooth audio profile data before reconnecting to your TV setup.
Likely causes
- TV HDMI audio format set to multichannel Bitstream/Dolby digital instead of PCM downmix
- Anynet+ (HDMI-CEC) protocol handshake failure between TV, HDMI source, and Bluetooth controller
- Samsung TV eARC passthrough mode blocking 2-channel Bluetooth audio output
- Corrupted Bluetooth pairing cache on the TV or Galaxy Buds
- Outdated firmware on Samsung Galaxy Buds or Samsung Smart TV mainboard
- Physical HDMI port banking interference or degraded HDMI high-speed cable
What's going on
When listening to external equipment—like a PlayStation 5, Xbox, or Apple TV—connected via HDMI to a television, routing audio to Samsung Galaxy Buds can fail. This typically isn't a dead earbud driver, but rather an audio transcoding breakdown. Wireless earbuds only accept a uncompressed 2-channel PCM stereo stream via Bluetooth. When an HDMI source feeds multichannel bitstream formats (such as Dolby Atmos or DTS) into the TV, the television must actively transcode and downmix that HDMI audio signal before beaming it to your earbuds. If eARC passthrough or Anynet+ (HDMI-CEC) configurations conflict with this pipeline, the result is dead silence or severe audio stuttering.
Symptoms people notice
- Complete silence in Galaxy Buds when selecting HDMI 1, HDMI 2, or eARC inputs, despite sound working on built-in TV apps.
- Audio cutting out every few seconds whenever video resolution or frame rate shifts on the HDMI source.
- Harsh static, buzzes, or metallic popping noises when launching games or movie apps on an HDMI console.
- TV status bar displaying connected Bluetooth headphones while no audio signal passes through.
- Unusable audio latency where sound lags several seconds behind the HDMI video feed.
Likely causes
- Incorrect HDMI Input Format: The TV HDMI port is set to receive raw Dolby Bitstream, which the TV cannot dynamically encode into standard SBC/AAC Bluetooth codecs.
- eARC Passthrough Lock: Enabled eARC passthrough forces the TV to bypass its internal sound processor, disabling Bluetooth transmitter routing.
- Anynet+ (HDMI-CEC) Handshake Errors: Control signals between connected HDMI consoles and the TV confuse the audio output pipeline.
- Glitched Bluetooth Cache: The TV or earbud memory contains a corrupted A2DP audio profile.
- Outdated Firmware: Software bugs in older Samsung TV firmware or Galaxy Buds software prevent multi-source audio conversion.
Quick checks first
Before digging into detailed menu settings, perform these rapid triage steps:
- Check built-in TV sound: Switch from your HDMI source to a native app like YouTube on the TV. If sound plays through your Galaxy Buds on native apps, the earbuds and Bluetooth chip are working fine; the issue is strictly HDMI audio routing.
- Disconnect extra Bluetooth devices: Ensure your Samsung earbuds aren't simultaneously connected to your smartphone or laptop via multipoint, which can steal audio priority from the TV.
- Inspect HDMI cables: Ensure you are using a certified Premium High Speed or Ultra High Speed HDMI cable. Faulty cables can drop HDMI audio control channels.

When it's a real hardware fault
If switching settings to PCM and unpairing devices produces no sound across any HDMI input or native TV app, you might be facing hardware degradation:
- TV Bluetooth Module Failure: The internal Wi-Fi/Bluetooth card inside the television may be failing under load or overheating.
- Defective Earbud Bluetooth IC: If your Samsung Galaxy Buds refuse to pair with any secondary device or constantly drop audio within three feet, the internal transceiver IC may be damaged.
- HDMI Port Pin Damage: Bent pins inside the physical HDMI port can disrupt the ARC/eARC pins (Pins 14 and 19) while keeping video functional.
Soft resets vs board/panel work
Fixing HDMI audio routing issues almost always comes down to soft resets and correct audio settings management. Adjusting HDMI PCM formats, toggling Anynet+, and factory-resetting earbud firmware through the Galaxy Wearable app solves over 90% of non-audio issues.
Attempting to replace internal TV mainboards, HDMI port banks, or micro-soldering earbud Bluetooth chips is complex and generally not a DIY task. If software resetting and PCM downmixing do not restore audio, consult official device support or refer to our device directory to explore tested hardware replacement options.
Next steps
- Open your TV settings and change all HDMI Input Audio Formats to PCM.
- Turn off eARC Mode in the TV sound menu.
- Cycle power on your HDMI connected source (console or streaming box).
- Reset your Galaxy Buds using the Samsung Galaxy Wearable app on your phone, then re-pair them directly to your TV.
