ALERT:  Impact of COVID-19

Due to the recent developments with the COVID-19 virus, we have implemented strict measures to protect the community at large and our employees alike.  Currently, we have very limited telephone support staff and you may experience longer than normal wait times.  However, we have many self-help resources available on our support site, and you can always reach us through e-mail.  We greatly appreciate your patience during this time.

I connected my sound bar to the TV via optical cable, but I don’t hear any sound

If you are not hearing any audio from the sound bar while connected to your TV via the optical cable, follow the steps below to resolve this concern:

  1. Ensure that the optical cables are firmly inserted into the TV and sound bar’s optical ports.
  2. Navigate to the TV’s setting -> Audio Setting and ensure that “S/PDIF and ARC” is set to PCM-Stereo
