Can I Use TV Speakers & Avantree Headphones Together? – Avantree Support

This is a TV based feature. Most modern TVs can play sound through both TV speakers and Optical Out (to your Avantree transmitter), but some TV cannot.

Option 1: Use Avantree Transmitter (Base Station)

This is the most reliable method and works with almost all TVs that have an Optical output.

LG TVs – Easiest Setup

Go to: Settings > Sound Out
Select “TV Speaker + Optical”
Done — both outputs work automatically.

Samsung / Fire TV / Sony / Roku / TCL

These TVs support simultaneous audio when set correctly:

How to Enable:

Go to: Settings > Sound > Expert Settings
Set Digital Output Audio Format → PCM
Set Sound Output → TV Speaker
(Optional) Unplug & replug the optical cable to refresh the signal

✅ PCM Format = Required
✅ Simultaneous Optical Output = ON (enabled by default on many Samsung TVs)
✅ TV Speakers + Optical Out = Both will work!

📝 Note: Some Samsung models include this under Settings > Accessibility
Look for “Simultaneous Optical Output” — make sure it's ON.

Option 2: Connect Headphones Directly via TV Bluetooth

Some newer smart TVs (2022+) support Bluetooth + TV Speaker at the same time.

Currently supported by:

Samsung (2022 & newer models)
LG (with Multi-Output Audio setting)

❗ Most TVs only support one Bluetooth connection at a time. This method only works if your TV explicitly supports dual output via Bluetooth.

⚠️ Still No Sound from TV Speakers?

Some TVs may not allow both outputs simultaneously. Try these options:

Option 1: Use a Soundbar / AV Receiver

Connect your TV → Soundbar (via HDMI ARC or AUX)
Use optical out from soundbar to Avantree transmitter
TV sound goes to both speaker & headphone = ✅

Option 2: Add Another Avantree Headphone

Pair an extra headphone to your system
Everyone hears clearly — no need for TV speaker
