I have a home theater setup with an ARC, 2 Play:1 as surrounds, and a Sub (Gen 3). Every day at the same time in the evening, the Sonos system turns on my LG OLED TV (OLED77C2PUA )
I have verified it is the ARC by disconnecting the HDMI cable between the two; TV does not turn on by itself when disconnected. ARC is connected via the Simplink port; if I connect via another HDMI port, TV does not turn on by itself, but the ARC will not turn on when I turn on the TV. I have deleted all of the components form the Home Theater setup, and recreated it. I have confirmed all firmware is up to date.
This week a news issue has cropped up; when whatever happens inside the ARC that turns off the TV, it is now also muting the home theater audio so it is at zero.
I have been troubleshooting this issue since June with Sonos, with no resolution. I just called for what seems like the 20th time for an update; this was escalated to Level 2 6-8 weeks ago. Offshore support says they will send an email two schedule a call, but no email.
Anyone from @Sonos monitor here? I have been a customer since almost day 1, owning countless Sonos devices over the years (Including the obscure CR200 remote), from the days when you talked to an engineer if you had an issue. The magic of Sonos has always been that it just works. I would like to buy a pair of Era 300s, but until I can get this resolved, I am more than a bit hesitant to do so.
