I am in the Caribbean on holiday for a while in case any answer needs me to be on UK Entertainment.

The Smart Box is working and I have good picture on Channels, but there is no sound. We also use Apple TV on this TV and sound is OK when using that service.

I have tried switching off the Smart Box and reconnecting, but still no joy.

Can someone give me any advice on this frustrating problem?

What Smart box?

How is it connected to the TV (eg SCART, HDMI or phono leads)?

What Audio Output format is it set to?

Need a bit more detail before anyone can give a definitive answer.

The box is a T8 Smart Box. I have no other information on it. . It is connected with an HDMI cable.. The Digital Audio Output is HDMI pass through.

I was able to use it when I was visiting about 6 months ago and do not think anyone has used it a lot. I cannot find any more details about the actual box, but we use Kodi to watch TV programmes

Sorry not to have more information, but it did work on s previous visit.

Can you change the Audio Output at all? See if it has an option such as PCM, LPCM, Stereo or similar. I suspect it is outputting a format the TV doesn't like. Forcing it to output plain vanilla stereo should work, if of course it has that option.

No I cannot find a setting that I can change. The sound is fine on all Channels in our local package and Apple TV also works well.

HDMI pass through is enabled. I have opened Kodi, gone into systems but as I have little technical ability I simply do not know how to fix the problem!

There is a Kodi Wiki here

That shows the various Audio settings available. This is accessed from the main page of Kodi click on Settings and then System.

Try setting Enable Passthrough to OFF and see if that has any effect.

Thanks for that information. Will try it out a bit later and will tell you if it works.

I do appreciate your advice
