Audio issue - sharp bleep changing audio output

[JP77]

Hi,

I have my Virgin setup with Sonos - a beam and 2 play 1’s. For over a year the sound has worked fine and I have follow content audio setting on so when switching from different channels/shows or app eg Netlfix I can see through Sonos it changed from Stereo PCM to Dolby 2.0 or 5.1. It did this fine and worked well. Just recently now when the audio output changes when I change channel theres a sharp bleep noise for 1-2 seconds which is pretty unpleasant and then the sound kicks in fine. I know there was a fairly recent update. Has anyone got any ideas? I don’t really want to have to just use Stereo PCM as that kind of defeats the point of having my surround sound! Thanks

Can you give this a try?  Change the mode to activte start and see if it is any difference tomorrow morning.

VM are aware even if it doesn 't look that way in this forum.

What power saving mode do you use?  Fast Start?

Yep!

Played with all settings and cables etc. Still the same problem! Think i’ll call for an engineer visit or something

Ah well I guess I call to report it so maybe they can look into it. Long shot I know!

Yes it’s fast start, thanks for continuing to try and help

Nope. No change and tried active eco and fast restarting in between changes

OK, I've found that the beep has sometimes gone after being in standby - but not 100%.

Hi @JP77
Welcome back to the community. 

Sorry to hear you're having issues with a loud beeping when changing audio output. Does this happen when the Sonos is not set up on the set top box? We can't support 3rd party device issues, but we will try help as best we can. If you do find a fix or workaround, do let us know so others in the community having the same issues can try your troubleshooting steps.

No it doesn’t but it isn’t a Sonos issue as it works fine on every other device. It’s only when running through Virgin and the audio is changing from a dolby output to a stereo pcm output. Thanks,

You mean the channel changing audio from PCM to DD causes the issue - which is what I can recreate??
