Silent movies might have been a big hit back in the 1890s, but nowadays, it's not very fun to watch a movie without audible dialogue. A thin flatscreen television may look great, but it often needs a high-quality sound system to get the audio it deserves. If you aren't hearing anything from your soundbar, there are a few troubleshooting steps you can take to get your talkies up and running again. Double-Check Your Inputs and Cables This may seem obvious, but make sure the volume is turned up and your soundbar is set to the correct input. If your TV is plugged into the soundbar's HDMI 1 port, make sure your soundbar is set to HDMI 1. If your TV is plugged in with an optical cable (also known as TOSLINK), look for an Optical or Digital In option. If your soundbar has a companion app for your phone, try using it to change the input, as it may be more reliable than the remote—or vice-versa. (Also, make sure the volume is turned up).
