No sound at all when Dolby Digital

I’ve got a Sonos beam connected to my tv, with two S2’s and a Sonos sub. I’ve been using it for a couple of weeks now and saw an article saying to check that it is playing in 5.1. I’ve checked and realised my tv was playing in PCM rather than Dolby Digital.

I’ve set out my set up below:
Samsung TV model UE42F5000
Amazon 4K Fire TV Stick
Sonos Beam
Sonos S2 x 2
Sonos Sub

My Sonos beam is connected to the TV via Dolby digital output, as this TV does not have a HDMI ARC.
The fire tv stick is connected in HDMI 1.
Everything else is set up and my TV was working fine, but it was using PCM instead of Dolby Digital.

I went to change my tv to DD from PCM but it was greyed out, until I then went on the TV stick settings and changed the settings under Audio > Surround Sound and selected Always Dolby Digital.

On my TV settings I clicked menu, then sound, checked my speaker settings are on external and then went to Additional settings where I could now select Dolby Digital.

Both seem to be on DD so I’m curious why no sound at all plays through my TV? Considering sound was working prior to these changes to settings, and works fine when I change them back.

I’d be grateful for any help, I’ll let you know any other details if you think are necessary but I think I covered everything.

Thanks,

Hi @Samgriffiths

Welcome to the Sonos Community!

Do you still have the TV and this problem? If so, I would definitely try unplugging the TV from power for a minute or two. I also recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system.

Be careful on the Samsung TV’s They can add a delay to the audio for external devices (DVDs Sky boxes etc), which cannot be corrected.

My model is Samsung UE40NU7120 has this issue. I had to add an optical switching box to direct Audio to my Playbase to stop the delay. Playing the Internal TV content and YouTube apps etc is fine. n I even bought a BEAM and connected via HDMI ARC and the delay was still present.
