Troubleshooting

Below are some of the most common questions people have during setup. You can find a full FAQ list at avantree.com/support/duet, or contact support@avantree.com directly for additional assistance.

Why don’t I get sound when watching Netflix / Prime Video?
You may need to change your TV’s audio settings an additional time when watching Netflix / Prime Video. This can be due to the movie being in Dolby Digital Surround Sound format, or because you’re watching with a separate streaming device / cable box. While Netflix / Prime Video is open, go into your TV’s audio settings and make sure that the audio output is set to “PCM/STEREO” and that “DOLBY” is turned OFF.

Other Tips:
If your TV’s HDMI ARC port is in use, your optical audio output port might not work. Try connecting the transmitter via RCA/AUX or unplugging the HDMI ARC.

It’s best to keep your transmitter at least 40 inches (1m) away from WIFI routers in order to avoid interference.
