Troubleshooting tips:
For "No Sound" issues on setup, reset LINK by holding down the button on the bottom of LINK for about 5-7 seconds until the white LED goes off, wait about 10 seconds and unplug LINK from the USB cord, wait and then plug back in. Re-assign each speaker slowly to allow the process to complete before assigning the next one. Make sure your Wisa speaker is in pairing mode.

Also, for LG TV first time setup, move LINK to a different USB port on your LG TV if you experience no sound or distorted sound.
