If My TV Doesn’t Have Optical Output How Can I Fix It?  

What-is-Digital-Audio-Out-in-Smart-TV

If your TV does not have an optical output, you may still connect it to audio and visual components using a few of the choices that are accessible to you.

The use of a digital-to-analog converter, or DAC, to change the digital audio signal coming from the TV into an analog signal is one of the most frequent ways this problem can be fixed. 

Connecting the digital audio output from the TV, which is often an HDMI or S/PDIF connector, to the input of the DAC and then connecting the output of the DAC to the external audio device is one way to accomplish this (i.e. soundbar, receiver, etc.).

Another option is to make use of an HDMI audio extractor to separate the audio signal from the HDMI signal that is being transmitted from the television.

 The digital audio signal that is transmitted over the HDMI connection will be extracted by the HDMI audio extractor, and then converted to an analog stereo signal. 

After that, the signal may be linked to the external audio equipment.

Last but not least, if your TV includes a headphone port, you may connect an adapter that converts headphone jacks to RCA to the headphone jack, and then use RCA cables to connect the external audio device to the adaptor.

 It will then be possible for you to send the audio signal from the TV to the external audio device using this method.
