I have connected echo studio to tv with optical cable it doesn't work what am I doing wrong
Hi, TIM MAR and welcome to the forums!
I'm sorry your TV audio is not working with your Echo Studio.
The optical jack on your TV is designed to output sound when the content you are watching contains digital audio. (PCM or Dolby Digital technology) This feature is available on select digital broadcasts and streaming video, and is not supported on standard cable or analog stations.
If the content does not contain a digital audio signal, then no sound can be heard through this connection. Additionally, sound sent to the TV through an HDMI connection or other input also may not output through the optical jack. (Check your TV's owner's manual or the manufacturer's website for more information on on this feature.) In this case, the optical jack from the source device (Blu-ray Disc Player, DVD player, cable or satellite box) should be connected directly to the Echo Studio.
Below are some possible causes for this issue:
The TV is not tuned to a digital channel.
The optical cable is not securely connected.
The optical cable may be faulty.
The TV may require a system software (firmware) update. Check the TV manufacturer's website for update information.
Ensure that your Echo Studio's power cord is plugged into a working outlet and and the device is powered on.
Make sure the optical cable is firmly connected to both the TV and the Echo Studio.
Try changing the channel on the TV or streaming content from another service.
Go into the Sound or Speakers menu of the TV and select External Speakers or Audio System. These names and the procedure will vary depending on your brand of TV. Check your owner's manual or the manufacturer's website for more specific information.
IMPORTANT: Some TVs require that the internal speakers be turned off before outputting the audio signal to another device. This step turns off the internal speakers.
