No sound on certain channels after system update today.

Userlevel 3
Hi, I received an app update today which also updated all the speakers software to v7.4 build 37244160. Since the update certain channels from my Sky HD box, such as Sky News & ITV4 take 60 secs+ for the sound to start. Other channels, BBC1 for example, the sound is present as soon as you switch to the channel. Nothing else has been changed in the setup. Any ideas before I start pulling leads. At the moment the playbar gets its optical from the TV, which has an HDMI source from the Sky box.

Hi I'm having the same problem - seems to be the HD channels only that have Dolby digital. I'm using a playbar with two play 1s for 5.1 surround. My diagnostic reference is 7814378. Thanks

LGE7 + SKY Q silver

Whilst on this subject, any news on dolby digital plus support? Sky Q now supports dolby atmos over dolby digital plus which the optical connection should be able to support via 2017 LG OLED'S at least.

I love my SONOS setup mostly but starting to feel it's getting a bit left behind.
