Hi @Czygen, welcome to the Sonos Community!

Sounds like there may be some settings we can check on the TV, mind providing the full model number?

I’d also recommend checking that the TV is providing a Dolby signal, rather than PCM - you should be able to check this in the Audio Output settings :)

Thank you for response.

Model is KDL40W705C

In Audio Output settings, choice is only Auto or PCM

Understood, I’d recommend setting the output to Auto.

It also looks like there are a couple of extra sound settings on the TV we can look at, specifically Sound Mode, Sound Booster, Voice Zoom and Football Mode - I’d recommend turning Sound Booster, Voice Zoom and Football Mode off completely, and seeing if there’s any improvement.

Thanks

These settings are unavailable when we use audio system, not TV speakers

The sound is still quite poor. Poorer than with TV speakers at the same level

It’s very deceipting

Got it - as the audio is fine with the DVD player, we’ll also want to take a look at the Orange TV audio settings - mind checking what they are currently set to? Do you have options for Dolby/PCM?

I see two settings :

which equipment is connected to your decoder : TV, Home cinema

If I select Home cinema : choose the mode of output : auto (to prefer if equipment permiits) or pass through (in case of sound problem)

Thanks - is there any improvement when selecting between auto & passthrough?

It may also be worth reaching out to Orange TV support, as the issue doesn’t occur with other devices connected to the TV such as the DVD player. Let us know how you get on :)
