Can I Use TV Speakers & Avantree Headphones Together?

Yes, but it depends on your TV model and settings.

Most modern TVs support playing audio through both the TV speakers + Optical Out (to your Avantree transmitter). Some older or budget models may not.

Option 1: Use Avantree Transmitter

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

• LG TVs – Easiest Setup

1️⃣ Go to: Settings > Sound Out

2️⃣ 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:

1️⃣ Go to: Settings > Sound > Expert Settings

2️⃣ Set Digital Output Audio Format → PCM

3️⃣ Set Sound Output → TV Speaker

4️⃣ (Optional) Unplug & replug the optical cable to refresh the signal

Important Settings:

✅ 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 allow only one Bluetooth audio output at a time.
This option works only if your TV specifically supports “dual audio output” via Bluetooth.

⚠️ Still No Sound from TV Speakers?

Some TVs simply do not support dual audio output. Try one of these backup solutions:

Alternative Option 1 — Use a Soundbar / AV Receiver

1️⃣ Connect your TV → Soundbar (via HDMI ARC or AUX)

2️⃣ Use optical out from soundbar to Avantree transmitter

→ TV sound goes to both speaker & headphone = ✅

Alternative Option 2 — Add Another Avantree Headphone

Pair a second headphone to your Avantree transmitter.

→ Everyone can hear clearly — no need to use the TV speaker.
