LG TV No Sound when Used with Avantree Transmitter
Step 1: Power ON the Transmitter Adapter.
Step 2: Make sure your Headphone/Speaker has been connected to your Avantree Adapter.
If your headphone is properly connected, the LED indicators on the Avantree Transmitter Adapter should be SOLID.
If you have trouble connecting the headphones, please visit the corresponding product SUPPORT PAGE.
Step 3: Connect the Avantree transmitter to your LG TV.
There are 3 ways to do it: Digital Optical (a.k.a. SPDIF or TOSLINK), 3.5mm AUX (sometimes labeled as HEADPHONES), and RCA (Red/White).
- Optical (SPDIF/TOSLINK)
- 3.5mm AUX (HEADPHONES)
- RCA (Red/White) - Needs to be labeled as "OUTPUT"
If you're using AUX or RCA, you should have audio through the headphones at this point.
For Optical, if no sound at this point, please proceed to the steps below.
Step 4: Adjust your TV Settings (so TV will send audio signal to its digital out port)
- Go into your Settings Menu, Select "SOUND"
- If there's a setting for DOLBY, switch it OFF
- Scroll down to "SOUND OUT"
- Choose "OPTICAL"
- Switch it to "PCM" (The adapter cannot transmit Dolby Signal)
Step 5: Reboot the Transmitter & the Headphone.
Turn both your Transmitter & your Headphone OFF, wait for a few seconds, and turn them back on again. Now you should be good to go.
