Morning all.
So, after a couple of hours of tinkering, I finally whittled the issue down to the Sky Q box.
I had originally stated that the issue was present with my Amazon Fire TV, however I tried it again as a part of my troubleshooting process and it worked ok, so this must have been a red herring.
In terms of other troubleshooting actions:
- Configured my Sony TV digital output to ‘PCM’ rather than ‘auto’ (no change - changed back).
- Changed my Sky Q audio output to ‘normal’ rather than ‘Dolby Digital’ (no changed - changed back)
- Changed my Sonos Playbar back to Wi-Fi (no change).
- Unplugged and removed the Play:1s from the setup (no change).
Finally, per my previous post, after completely resetting the Sonos Playbar and creating a new system (minus Play:1s), the problem persisted.
As a last resort, and having read previous posts about wireless interference, I decided to have a play with the Sky Q engineers’ menu and see what I could configure there.
Because I have (almost) everything hard-wired, I have no need for the Sky Q to be sending or receiving Wi-Fi, so I switched-off the 2.4 and 5GHz wireless settings. Et voila! No problems since (touch wood!)
As a side note, I hadn’t changed anything prior to this issue occurring, so I am none-the-wiser as to what caused it.
