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.

Alrighty, as of this post, everyone in the thread should be marked for the beta update for this issue. Please check for updates in your system and you should be all set.

For those of you waiting who might not want to join the beta, testing has been going great and we'll be having a full release for this very soon. If all goes as planned I'll have some good news for you shortly. Again, our apologies for the trouble.

This is the second time in posting this info in this forum in an 8 day period. I hope they do something this time.

I just double checked, your system was flagged for the beta that fixes this issue on the 25th. Make sure you check for updates in your Sonos app under Settings, there's one that's been waiting for you that fixes this issue.
No sound just ticking when playing YouTube videos, all other sources seem fine.

Hi there SkyFireXl, jmpacker13, cornerstone, Fixy999 & tylerherzog1:

I'm having the same audio issues. My diagnostic number is 7907221. Thanks!
Please send the beta: 7907250. Thank you.
I am also having audio out problems post 7.4 Sonos update.
I have a Samsung UA55JS9000 TV connected to my Sonos playbar via optical. The TV channel sound is fine, however if I access content via smartTV apps such as IVIEW, SBS on demand or YouTube, I do not receive audio output. I can receive audio if I select TV speakers over optical out and do not use the Sonos bar. I have run YouTube via my PC through the TV by screen mirroring and sound is ok through Sonos. System diagnostics: 7907272
Sony Bravia KD-55X9005
playbar - router sub/play3 surrounds
playbar direct to tv via optical

Long lag before audio kicks in (netflix tv app). Will be fine then drop out when we change show.
