Sonos Arc keeps losing TV connection and shows connection issue

Im having the exact problem with my Samsung Q95T tv I got last week. The HDMI-earc connection keeps dropping. Even though I have not changed a thing and the only thing I did was turn off the tv & start again.

I think it’s definitely a Sonos problem and not a Samsung one. The issues had settled down and not happened for a while….. until my wife touched a button on top of one of the surround Play1’s a couple of weeks ago -now problem back, every day now for 10 days! Getting ridiculous. Am now changing out my Sonos gear around the house for other alternatives-enough is enough!

Just got the Sonos Arc SL and having the same issue connected to a Vizio tv. It works fine but if I turn off the tv or switch to another device and back to the tv it quits working. I have to unplug all other hdmi cables and reboot the tv and plug the hdmi cables back in. Can’t believe we have to deal with this after spending $800 bucks on a soundbar 

I’ve got two Arcs, both connected to Vizios of various vintage, and am not experiencing this issue on either set. 

I’d be checking to see if there is an update to the firmware on the Vizio, and then if that didn’t fixit, I’d be testing removing of devices connected by HDMI, one at a time, and then testing, to see if you can identify which device feeding the TV is the issue.

It sounds like you’re having CEC issues, and some devices don’t have it implemented properly. If you can, you might possibly turn off CEC on all devices connected to the TV, leaving just the TV’s CEC turned on, which it uses to connect to the Arc. 

I am having the same problem with my Samsung tv. Works great for awhile, then the Arc Sldisconnects from the tv for no apparent reason.

Sorry to hear that-that’s exactly what I was getting, plus the failing to connect when turn TV on. Only fix was power everything off at mains.

It feels a bit naughty Sonos can’t throw any useful light on it. I have now returned my Arc, and bought the Samsung Q900T instead-I think it’s actually better than the Arc-and it actually works! 

Maybe if everyone started returning them Sonos might acknowledge there’s an issue. Shame really!

Yeah, I would return my arc as well if it wasn’t already outside the return window. I’m having the same connection issue with my Sony tv all of a sudden. Worked fine for about 6 weeks before this started happening. 

Sonos Arc working fine, and upon returning home after five days, Arc won’t connect to Sony XBR75X900E. Replaced HDMI cables, reset Arc, checked all settings and gone through setup process multiple times, but Arc won’t connect. Sonos Support unable to resolve. This just HAS to be a software issue. Why can’t Sonos figure this out? Very frustrating. 

Same issue with my QLED. Looking back I read and ignored the warnings about the Arc losing sound and connection. I would avoid until they find a fix for this issue. Way too much money spent to have to deal with this many problems.

BKBarclay,

Have you rebooted the TV?

In other online communities there have been reports of difficulties with SONY TV’s and audio output, not only when used with SONOS. Various “solutions” have been reported, ranging from TV factory reset, TV firmware update, switching to the optical connection, and replacing the SONY TV’s motherboard.

Have you tried using the optical connection between the TV and ARC?

While I have no proof, I would place this issue with SONY. I don’t know if SONOS can come up with a work around. With HDMI in general there can be issues with “EDID”. EDID is a protocol where HDMI devices share their capability with each other. When EDID works, it prevents box ‘A’ from sending an unsupported audio or video format to box ‘B’. Unfortunately EDID is notorious for getting mixed up or not reporting anything between the boxes. You can force renegotiation by momentarily interrupting the HDMI connection. This issue is common enough that there are accessory boxes that can added in order to force EDID renegotiation by remote control.
