No sound coming from soundbar

Here are steps to connect a Samsung soundbar to a Sanyo FVM3982 TV using an optical cable:

1. Locate the Optical Out port on the back of the Sanyo TV. This port will be labeled "Optical Out" and is usually covered by a small protective cap.
2. Remove the protective cap from the Optical Out port and plug in one end of the optical cable.
3. Connect the other end of the optical cable to the Optical In port on the Samsung soundbar. This port may be labeled "Optical In" or "Toslink".
4. Turn on both the TV and the soundbar.
5. On the Sanyo TV, use the remote to navigate to the audio settings. Look for an option to set the audio output to "External Speakers", "External Audio", or "Optical Out". Select this option.
6. Adjust the volume on the Samsung soundbar using its remote control.

Once these steps are completed, the sound from the TV should be played through the Samsung soundbar. If you encounter any issues or don't hear any sound, check to make sure that the soundbar is set to the correct input and that the volume is turned up. Additionally, make sure that both the TV and soundbar are properly connected and powered on.

You have to go into the audio set up screen on the TV and direct TV sound to the output cable connector you used for the sound bar. Example: Optical, digital.

I am going to guess here that you are running this through an audio system or a cable box. Your audio needs to come form the source, not the TV. Ex. If you were to go optic cable out of your cable box and into the TV optic then you would get sound out of your TV speakers. Go direct to sound bar.

If you are connecting the soundbar to your TV with the digital audio cable, make sure to select "D IN" using the source button on the soundbar. Bluetooth (BT) is a separate source from another device. (phone, etc.) The TV will need to be set to use the digital audio output and probably PCM format. (?) The subwoofer is preconfigured at the factory to mate up with your soundbar. (See below instructions - your soundbar includes the amplifier:)

Digital audio output setting:
After connecting an amplifier with digital audio input and
external speakers as shown, you should set an audio
output format compatible with the programme you are
watching or the device connected.
Go to "HOME" > "TV Menu" > "Setup" > "Option" >
"Terminal setting" > "Digital audio output" > select
"PCM" or "Bitstream".
NOTE
• When set to "Bitstream", Dolby Digital is output when the Dolby
Digital or Dolby Digital Plus audio formats are received. When
set to "PCM", PCM is output no matter what audio formats are
received.
• When set to "Bitstream", HE-AAC audio formats can be output
as Dolby Digital.

Does your TV have a Digital optical port? It's a cable that sends a red light source. That is actually how you're suppose to hook up a soundbar. digital optical cable Bing images Straight forward. Plug and play. If you're TV doesn't have an optical port, as I know your soundbar does then you have to use a stereo Y Cable. 3.5mm to Red/White. Sound bar will have 33% the power going this way as opposed to an optical cable. Aux Audio Out has a itty bitty amp pushing power. Purpose of the Digital optical Cable is a light source.

you could try to hook up with the HDMI connection if fitted.

You may need to enable sound output in the tv menu

Arc ready is when there is electricity plugged into the TV,There is only one HDMI cable and that is the one you have. Cause all new TV's come with these cables.If you are using Av cables for the sound it will not work ,you must only use HDMI cable's.Cause some or most new TV's with HDMI dont like to use Av cables with HDMI,so if you havw something else that uses Av cables plug it out and sound will work.

On the Sony The HDMI takes "priority" over all others, that's why you loose audio. If you run your DVI/HDMI to the TV and optical to the soundbar that would fix your issue. If your TV does not have Multiple HDMI inputs, you can get a DVI/Component adapter for your MBP then run it to the TV, or, If you have to have HDMI just to have HDMI, you can get a 2:1 HDMI switch and still have optical to your soundbar. Make sense? If youneed more help, just post a comment and I'll help some more.
