LG soundbar with PS5 audio delay: what’s actually happening?
If your PlayStation 5 sounds slightly behind the action, the problem is usually not the soundbar alone.
An LG soundbar with PS5 audio delay is often the result of HDMI handshakes, audio format mismatches, TV processing, or game mode settings that introduce latency.
The good news is that most delay issues can be reduced or eliminated with a few targeted changes.
Understanding the signal path from the PS5 to the TV and then to the soundbar is the fastest way to fix it.
Why PS5 audio delay happens with LG soundbars
Audio delay, also called lip sync delay, occurs when the sound reaches your ears slightly later than the video reaches your eyes.
With a PS5 setup, that delay can be created anywhere in the chain: the console, the TV, the HDMI connection, or the soundbar itself.
- HDMI ARC or eARC processing: TVs may buffer audio before sending it to the soundbar.
- TV image processing: Motion smoothing, noise reduction, and enhancement features can slow video or audio paths.
- Audio format conversion: PCM, Dolby Digital, DTS, and Dolby Atmos can behave differently depending on device support.
- Wireless interference: Bluetooth connections create much more latency than HDMI or optical.
- Game mode conflicts: Some TV picture modes reduce video lag, but audio settings may still be out of sync.
Best connection methods for PS5 and an LG soundbar
The connection method matters more than most people expect.
For the lowest latency, HDMI eARC is usually the best option if your LG soundbar and TV both support it.
1. HDMI eARC
eARC supports higher bandwidth and better format pass-through than standard ARC.
It is often the preferred route for Dolby Atmos, multi-channel PCM, and cleaner sync behavior on modern LG TVs and soundbars.
- Connect the PS5 to the TV’s HDMI 2.1 port.
- Connect the LG soundbar to the TV’s eARC HDMI port.
- Enable eARC in the TV sound settings.
- Use a certified high-speed HDMI cable, especially for 4K 120Hz gaming.
2. Standard ARC
ARC can still work well, but it may be more limited in bandwidth and format support.
If your TV or soundbar does not support eARC, ARC is the next best wired option.
3. Optical
Optical avoids some HDMI handshake issues, but it usually does not support advanced formats like Dolby Atmos from game consoles.
It can still be a stable fallback if ARC introduces delay.
4. Bluetooth
Bluetooth is the least suitable option for PS5 gaming because it adds noticeable latency.
It is fine for casual audio, but not for fast-paced games where gunshots, footsteps, and dialogue timing matter.
PS5 settings that can reduce audio delay
The PS5 offers a few useful audio controls, but they only help when matched correctly to your TV and soundbar setup.
Small changes here can make a big difference in sync.
- Settings > Sound > Audio Output: Confirm the correct output device and HDMI device type.
- Audio Format: Try Linear PCM first for the cleanest signal path.
If your LG soundbar setup prefers compressed formats, test Dolby Digital as well.
- Enable 3D Audio only if needed: Some users prefer standard output for simpler sync behavior.
- Adjust output to your setup: If the PS5 is connected to the TV, let the TV handle passthrough instead of forcing unusual output paths.
For many players, Linear PCM provides the most responsive sound.
However, if your LG TV or soundbar has trouble passing PCM through ARC, Dolby Digital may be more stable.
LG TV settings that matter most
When using an LG soundbar with PS5 audio delay, the TV is often the middle point where lag appears.
LG TVs include several sound options that can either help or hurt synchronization.
Enable passthrough or eARC
Set the audio output to pass through instead of processing the signal internally when possible.
This helps preserve the original timing from the PS5.
Check lip sync settings
Many LG TVs include an AV Sync Adjustment or lip sync slider.
If dialogue trails the action, lower the audio delay; if sound comes early, increase it slightly.
Use Game Optimizer or Game Mode
Game Mode reduces input lag on the video side.
This does not directly fix sound delay, but it can improve overall sync by reducing the delay introduced by TV picture processing.
Disable heavy video processing
- Motion smoothing
- Noise reduction
- Dynamic contrast
- Extra sharpness processing
These features can make sync issues more noticeable, especially in fast action games and sports titles.
LG soundbar settings worth checking
LG soundbars often include sound modes and processing features that can affect timing.
If audio feels behind the gameplay, simplify the soundbar’s signal chain first.
- Set sound mode to Standard or Direct: These modes usually add less processing than surround or cinematic modes.
- Turn off extra enhancements: Features such as virtual surround or AI-based processing can increase delay.
- Check firmware: Update the soundbar through the LG app or support tools when available.
- Confirm input source: Make sure the soundbar is receiving audio from the intended HDMI ARC/eARC port.
If your model includes a dedicated AV Sync control, use it sparingly and make small adjustments.
Large corrections can hide the problem instead of solving it.
Step-by-step fix for LG soundbar with PS5 audio delay
- Connect the PS5 directly to the TV with a high-quality HDMI cable.
- Connect the LG soundbar to the TV’s ARC or eARC port.
- Set the TV to Game Mode or Game Optimizer.
- Disable motion smoothing and unnecessary image processing.
- Set the PS5 audio output to Linear PCM and test.
- If sync is still off, try Dolby Digital and compare results.
- Enable pass-through or eARC on the TV.
- Use the LG TV lip sync feature for fine adjustment only.
- Update firmware on the PS5, TV, and soundbar.
When the delay is only happening in certain games
Not every title behaves the same way.
Some games have built-in audio latency, different cutscene rendering, or more aggressive effects processing that can make delays easier to notice.
Competitive shooters, rhythm games, and racing games tend to expose sync problems more than slower single-player titles.
If the issue appears only in one game, test the same setup with another title before changing hardware.
That helps separate a system-wide audio problem from a game-specific rendering quirk.
Signs your setup needs a hardware change
Most LG soundbar with PS5 audio delay problems can be fixed in settings, but a hardware upgrade may be worth considering if the issue persists.
- Your TV lacks eARC and only offers basic ARC.
- Your soundbar does not support the formats you want to use.
- You rely on Bluetooth or mixed adapters.
- The delay remains noticeable after firmware updates and AV sync tuning.
In those cases, a newer HDMI 2.1 TV, an eARC-capable LG soundbar, or a direct connection strategy may provide the cleanest result.
Quick checklist for the fastest troubleshooting
- Use HDMI instead of Bluetooth.
- Prefer eARC over ARC when available.
- Connect the PS5 to the TV, not directly to the soundbar unless your setup requires it.
- Try Linear PCM first, then Dolby Digital.
- Enable Game Mode on the TV.
- Turn off motion smoothing and other video enhancements.
- Adjust AV Sync in small increments only.
- Update firmware on all devices.
With the right connection path and a few careful settings changes, an LG soundbar can deliver tight, responsive PS5 audio without the distracting lag that ruins immersion.
