Potential Major Issue with 2020 Samsung tv's with One Connect and eARC

[Mike2020]

Hi All

Posted previously about my experience with a Q95T and Sonos Arc, and connecting via eARC. On enabling eARC to Auto on the Sound Settings, no sound is output from the device and thats from any source, in built apps/Dolby Atmos/4K Blu etc.

On turning eARC off, sound is restored through the soundbar.

I have contacted Sonos and Samsung directly with both blaming the other party for the issue and that's disappointing. 

On discussions with both communities, it now appears that users with the Q80T can connect via eARC, however many users with Q95T and Frame 2020 models cannot get sound via the eARC so potentially a big issue.

This also now sounds like a Samsung issue, as the standard eARC function not talking to the Sonos Arc via one connect, but other Samsung models are talking to Sonos Arc. I have seen evidence of this on a Q80T where eARC is working and the device shows as Reciever (HDMI eARC), on the Q95T, on setting to Auto you get Reciever HDMI.

Can this be escalated to samsung please as quite a lot of users are affected and returning tv's for other mfrs models?

Thanks

Mike

Can your TV pass through multichannel PCM via eARC? 

Or you are talking about internal sources?

Thanks

Not good enough is it.. hope you don’t expect a response from Samsung though as you’ll be waiting a while

Sonos Arc with new FW-release today, R 12.2.2 

Samsung Q95T also with new FW-release today, R 1460.9

It looks and sounds good. No sound gaps so far after the upgrade.

Intrigued mtb_fh. You say it’s fixed? Any release notes available as I can’t find any? I’d heard this would be a challenge through firmware as others allude to a hardware fault with One Connect cable. Keep us posted for next couple of days please. Irrespective I’ve still returned my unit to consider options again.

Also updated with both new firmwares tonight, Frame 65” 2020 and Sonos Arc. Still sound gaps when playing Atmos material. The first one occurred after about 1 hour. Amazing how badly this is handled by Samsung. 

[Scoops77]

Did you do a hard reset including unplugging all the cables, re-plugging only Arc in first etc. etc. that old irritating rigmarole many of us on here have likely been through multiple times?

[Jocke]

Nope, I’ll try that tomorrow, but not very optimistic though. 

[mtb_fh]

Sorry, a bit too optimistic yesterday. 

With 2 x new FW yesterday, sound was ok without any power cycle. Sound ok even after turning system off and on several times. 

Turning system off overnight, and sound-gap is unfortunately back today. 

Unplugging and re-insert power on the Sonos Arc once again the solution, so back to normal. Obviously a hand-shake-issue between Sonos and Samsung when both starting up from idle and using HDMI-3. So back to optical. 

[Jocke]

Restarting and unplugging cables didn’t help either...

Same issue with q80t and Sonos Arc. Both updated yesterday to the latest firmware versions. Thinking about returning the TV as it is still possible for two weeks. Reading all comments here makes it hard to believe for me that Samsung will provide a fix anyway.
