Sonos Beam ARC Sound cuts out at 9pm Every Day

Hi community!

 

I’ve got this really weird problem that’s started happening recently, let me describe my setup first.

The Setup

  • Sony TV KD-49XF7093
  • Sonos Beam (1st Gen)
  • Apple TV HD

The Apple TV is plugged in to the Sony TV with a HDMI Cable. There is then a HDMI cable from the ARC out on the Sony TV to the Sonos Beam.

 

The Problem

 

For the last 2 weeks, every night at 9pm sharp the audio stops on the Sonos Beam, the TV Speakers become Active, and then back to the Sonos Beam, all within about 2 seconds. you can clearly hear the sound difference in the room, recording it on my phone only really shows the messages that pop up, it’s difficult to hear the sound dipping in and out given the recording of the show that I did.

Things I’ve tried

  • Rebooting Sonos
  • Turning TV off at the wall
  • Swapping HDMI Cable (ARC)
  • Updating TV
  • Updating Sonos
  • Updating Apple TV
  • Changing the time on the TV to trick it not at 9pm
  • Speaking to Sonos who believe it to be network related (I still can’t get my head around this) - they’ve asked me to reboot every other speaker in my house because they could see wireless interference. My mind is still bending as to how that could effect a HDMI cable providing audio. Honestly, I could go full rant about this. They’ve even suggested I change wireless channel.
  • Sent diagnostics to Sonos for the Beam.
  • Sonos have suggested I test it again tonight, after rebooting all speakers in the house.

So, calming my annoyance about the network interference on a HDMI connected device, I’m currently at a bit of a loss. I’ve just planned to call them back tomorrow being pretty confident in my thoughts that todays troubleshooting won’t of fixed it.

 

Why on earth would it be 9pm every night? What could possibly be causing that blip?

 

I’d be interested to know your thoughts and ideas.

    Update 4 - Final Update

    Well, I’m eating my words, annoyed at myself but finally have a solution. Though, the logic of it still baffles me.

    Last night I set things up for tonight’s test: 

    • I disconnected my TV from the Wi-Fi
    • I took on board all your suggestions, I had a Tapo wifi plug upstairs that was powering an extension lead to my desk; including 2 Sonos Bookcase speakers. This Tapo plug was set to power off at 9pm every night… can you see where this is going? So I set this plug to go off at 9:05pm tonight.

    Guess what happened? The audio interruption happened at 9:05pm on the dot.

    • Why turning off speakers in another part of the house causes a physical audio blip, I don’t understand.
    • I am putting my hands up and admitting I was wrong to question the whole network thought process. It doesn’t make sense to me, but, it’s obviously what’s happening.

    I would like to caveat that I have the same plugs in several rooms around the house, and all on timers for various things. None of them have the same interference issue so it’s lead my to believe that 2 Sonos speakers disconnecting from the network at 9pm is causing this blip. Why it interferes with a HDMI connection, I can’t understand - to my mind Sonos should address this, as it should be independent of any networking capabilities.

    Any way, with egg on my face - but happy to have resolved it, I’m calling time on this one!

    Thanks all for your continued thoughts and help!

    Could this be electricity related? A short power outage or signal sent through the power network?

    Update 3

    I spoke with Sonos again, I think I got sent through to their senior support team.

    • They’ve looked at the diagnostics I submitted straight after it happened; there’s no network issue occurring and no power blip. 
    • They have said there’s possibly a signal issue from the TV but can’t confirm. They’ve asked me to speak to Sony and if they can’t see anything, to go back to Sonos to escalate it to their dev team to do some bug investigation.

    To answer everyone else (thank you for your comments)

    • No parental controls in play
    • No IFTT / automations etc in play
    • I do have Spotify Connect but nothing that’s triggering anything from what I can tell
    • No other devices are on any schedule for 9pm
    • No other power related issues
    • Strange it’s only started happening over the last few weeks, I can’t think of anything that happened around the time it started - no new devices etc on the network.
    • For info: when the speaker cuts out and then goes to the TV and back, the sound never stops, just changes where it comes from.

    I’ve now turned off the WiFi on the Sony TV as per @GuitarSuperstar suggestion, we’ll see how it goes tonight!

     

    For info, here’s the video of what’s happening - you’re welcome Office fans :)

    It looks like something is momentarily stealing the HDMI-CEC focus for a second or so, looking at that video - but you disconnected your only HDMI connected device, which you mentioned, which is the Apple TV, so it’s still quite baffling. So there are definitely no other HDMI connected devices to the TV, such as a Cable TV box etc?

    Unless it’s some kind of CEC refresh that the TV does once a day, but what a strange time of day to do that anyway. 

    My only other thought is that the TV is perhaps renewing its ‘leased’ IP address and if disconnecting it from the network resolves the issue, then try increasing the routers DHCP servers IP address leasing-period from 24 hours to some greater time value and see what effect that may have on the issue.

    It’s not a good idea to have your Sonos speakers disconnected from power on a daily basis.  This isn’t a recommended practice, so I can’t see Sons making changes that support that.

    I would definitely put these on a different plug.  At the very least, you would confirm that it’s the speakers leaving the network (due to no power) that is causing the blip and not some sort of electrical issue that is causing the TV to drop the connection.
