Quartet 2 - Fix One Side Sound – Avantree Support

One-Side Sound

Start With the Audio Cable

If sound is only coming from the left or right side, the audio cable may not be fully connected.

Most common cause: a loose cable connection.

If the cable is only partially inserted, the left or right audio channel may not come through.

Check the cable before changing any other settings.

Unplug the audio cable from the transmitter, then plug it back in firmly.

Repeat this 3–5 times to make sure the connection is seated properly.

Make sure the cable is fully inserted into both the TV or audio source and the transmitter.

Push the connector in firmly until it is fully seated.

Gently move the cable near each connector while audio is playing.

If the sound cuts in and out, the cable or connection may be causing the problem.

Turn the headphones OFF, then turn them ON again and test the sound.

Connect the AUX cable directly from your TV or audio device to the headphone AUX port and test the headphones in wired mode.
