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?
Having the same issue.
Just wanted to ask, what firmware update is your Q95T? Mine is only at 1302. Wondering if you’ve updated yours to 1304.
Stumbled on this thread after many hours of troubleshooting my 2020 75" Q7DT eARC issues when connecting to my Marantz SR5014 AVR. I spent many hours swapping cables, factory resetting devices, tweaking settings, etc; only to find out that at least according to this thread, the Samsung needs to provide a firmware update to "fix" the eARC issue. My TV very recently updated to 1301.5 (released Aug 4) and still isn't playing. As it stands the TV has only the HDMI 3 (eARC) port in use and attached directly to the Marantz AVR.
Very frustrating indeed since I can only use PCM audio from the TV. Passthrough is greyed out.
I see a new firmware for the Frame 2020 is available as of this morning (Sept 29th, 2020). Its not available for auto-update on the TV itself, I'll have to do a manual update later this afternoon to test it out. Fingers crossed this will fix the issue.
Here's the firmware download section: https://www.samsung.com/us/support/downloads/
