Sonos turning off Bravia TV

49 replies
8480 views

Just got a Sonos Beam. Connected it to a Sony Bravia TV using HDMI ARC and set up Bravia Sync. Audio is playing great. The TV remote, Apple TV remote, etc can control the Beam volume just fine.

However, I’ve noticed that lately the TV is doing what I might call a “hard power down” after sleeping, but only after having slept for some time. By hard power down I mean that next time I try to turn the TV on by waking a Bravia Sync device (like the Apple TV), the TV won’t turn on like it did before the Beam was added. And when the TV does turn on (which requires using the TV remote), it shows the Sony logo, the Android logo, the four rotating color block animations, etc and takes a minute or so to load.

My hunch is that the Beam is somehow sending a CEC power down signal to the TV, and the TV is interpreting it as a hard power down.

This only happens after the TV is off for an extended amount of time (an hour or two).

Any ideas?

Ok so I switched to connecting the Beam to the TV with the optical adapter. The rebooting problem stopped (since Beam can’t access the TV using CEC). After playing with a few settings, it seems like this works just fine with only one major downside vs. using ARC/CEC.

For the settings changes:

For each input and the built-in Apps, turn off Clear Audio, set output to Dolby Digital, and set Speakers to Audio System
Make sure “Use IR” in on in the Sonos app
For me, the TV remote and Apple TV remote could control Sonos volume using IR (not sure if this will take extra steps for you), and the DVR remote controls Sonos volume using IR when you press the TV button first (assuming it’s already set up with the TV remote code as a universal remote).
Set up Sony’s Android TV skill in Alexa since Sonos can’t control the TV directly over optical (but since Sonos acts as an Echo it works just fine indirectly)

EDIT: See below for fix on this. The only weirdness seams to be that the on-screen volume meter doesn’t stay synced with the actual Sonos volume. So while up and down always effectively work to increase/decrease Sonos volume, and anything that moves the TV volume meter up/down will increase/decrease volume Sonos volume, you could get into situations where the TV says “0” and you aren’t at minimum Sonos volume (but you can keep pressing down to decrease volume), the TV says “100” and you aren’t at maximum Sonos volume, (but you can keep pressing up to increase volume), and things in between won’t consistently match to an actual Sonos volume (so “25” on the TV may be really quiet, or really loud).

I was just told by Sonos support that it’s Sony’s issue so deal with them or use optical.. sigh.

The beam is the thing causing it though. Doesn’t happen when the beam is removed. Doesn’t happen with a different sound bar. Returning this weekend even though I really want to keep it.

I totally agree. It seems like the issue started a couple of weeks ago. I wonder if there was a beam update around that time.

How long you had the tv and beam set up? Was fine before a couple weeks ago? Could be either a Sony or Sonos update that changed something.

Just a few days- however I’ve noticed that this thread and the thread on the Sony website both started a couple of weeks ago

Did they say why it’s Sony’s issue? If I have to go back to Sony it’d be great to explain what the problem seems to be so they can address it.

Yes, they stated that the Sony TV is “forgetting” the Sonos and thus thinks it’s a new device- hence initiating the restart. This explanation is problematic for a host of reasons. I felt like they were trying to get rid of me tbh.

Is it happening to any TVs other than Sony? If so, it could be a Sonos issue. If not, it’s liable to be a Sony HDMI-CEC issue. Might be worth double checking to see if there are firmware/software updates for the TV, just in case.

Yes I just updated my firmware to their latest version via USB but I’m sorry to say it still has the issue.

I have an XF9005 (with Sonos beam) that was doing this exact same thing. I was also experiencing some wifi stability issues. In the end, i disabled the TV wifi (now use apple TV 4K) and this actually resolved my rebooting issue. Just thought id put this out there in case it can help anyone else.

The one problem i still have is when turning on the TV using alexa, the TV will turn on but then instantly turn off (only a soft turn off). If i use alexa to turn it on again it will stay on. The problem ususally happens when the tv has been off for a few hours.

How long has it been since it rebooted after turning off wifi? I’ve tried changing setting on the tv, sometimes can go 3 or 4 days, but reboot always came back.
