I have a Sonos Playbar/Sub/2 x Sonos 1s setup with my Samsung F8000 TV.
Previously I had SkyHD and things worked fine as follows:
SkyHD > TV > Sonos
The TV passes through DD to the Sonos system and all was well.
I've just had Sky Q installed and have left the wiring as-is. The sound works, the Sky Q remote controls the Sonos volume with no problem, however when changing channels or when starting YouTube on the Sky Q box I get a loud 'pulsing/chugging' sound coming from the Sonos kit until the channel is fully changed (or the YouTube app is loaded). Sky Q is configured to pass DD through HDMI.
Connecting the Optical connection directly from the Sky Q box to the Sonos kit (not via the TV) solves the problem, but I want to use smart apps on the television also (playing from DLNA sources, Netflix, Amazon Instant Video, etc.)
I guess I have a few questions:
1. Am I alone? Or does this happen to others
2. I assume this is an issue with Sky Q and not Sonos, as the Sky HD box didn't have the same problem with the same connection scheme - but I'm not certain.
3. If I live with it for now, is the noise likely to damage my Sonos kit?
4. Is there any way to overcome this or correct it?
