Don’t worry about the lower cost. A more expensive cable doesn’t always mean you are getting better quality. My cables aren’t very expensive but they work great. The audio playing from my Arc sounds incredible. And just the other day, someone was very surprised that my TV was not 4K because the picture quality looked so good.

Yes, this is correct. Try unplugging everything from power for a couple of minutes and test again.

What cables are you currently using?

I am currently using these…. Current cables

I have also used these…. Old cables

Thanks for your input….

I have asked them this very same question….

Its quite baffling that a cheaper cable will work better than a more expensive version?

I’m just concerned that I won’t get the full audio/visual experience I should be getting?

You are probably just experiencing what is described below which is completely normal with the Arcana:
 

From the Arcana manual FAQ:

I notice a short black screen / resync when starting a content that i didn't have or noticed when connected direct to TV?
All that is normal, you will have the same if you insert any device in between, like an AVR, splitter, matrix, switcher, video processor, and the more device you have in the same chain, the longer this will take, the only way to have that nearly not noticeable is SOURCE > DISPLAY direct since signal goes straight to panel driver. If menu is 60Hz and content 24Hz then there will be a resync like for any video format change, if you have SOURCE > TV, then sure you never noticed it but insert any device in between and you will have the exact same, just normal, HDMI resync.

I noticed recently that the application correctly displays 5.1 at least sometimes. I haven’t updated the Sonos equipment or the app in awhile though. I have everything on 14.10, so I’m not sure about the latest software. It seems to be working for movies and on the Nintendo Switch. I haven’t done any deep testing on it, though. It has been claimed to have been working all along, so perhaps just a display error on the application side. I’m still using the Dr HDMI 4K to get it from the UB9000 through the LG G1 to the Sonos soundbar, though. I haven’t noticed any issues, just have to turn it up really loud for DTS audio surround movies in comparison to Dolby tracks.

Has sonos sorted this downmixing issue out yet, does anybody know? I know since they have released basic DTS support but wondered if this issue has been fixed and if I use a blu ray which has 7.1 what will that come through as? 

Check out this thread @SeafordMick . You might not find the greatest news, but it might help you try some things and/or understand the situation a bit better. I also have a UB9000, but a G1 instead of a C1. I believe the problems would be the same for you. In a nutshell if you don’t want to try the stuff mentioned, we can get DTS conversions to Multichannel PCM with some effort (and more gear), but it always comes through as 7.1 which leads to some missing sounds. Sonos has mentioned that they are working on downmixing to 5.1, but no timetable. I’m hoping soon.

Hay all. I have the same problem, I have an LG C1 Oled with the Sonos arc and a UB9000 every time I play any DVD with DTS ITS IN Stereo PCM 2.0 only, it’s driving me crazy now

The TV is set to pass through as well. 

Whichever you prefer, or whatever works best for your setup.

Do you leave your switch on all the time or is it safer to put into standby?

It’s an audio cut off, which would make sense with the info you sent me….

Another strange thing I noticed is the Sonos S2 app is no longer showing my Arc/Sub/One SL rears on the app?

Ive reset the app, but still nothing showing up on the app?

Is there an actual audio delay or does the sound just cut out for a few seconds while the Arcana is resyncing?

Thanks for finding that out for me….

It does seem to ease off after watching the channel for a few minutes, but every time I switch to the Sky Q main menu & back again, there is a slight delay….

Is the TV set to the correct HDMI input?

The correct audio is coming via Sky Q, I’ve checked Atmos films & it works, although the Sonos app just had a wobbly, so I have reset it.

The sound drop seems to happen when I enter the Sky menu (home button) & then exit it, almost as if it’s lost connection?

Are you getting the correct audio from the Sky Q? Does this only happen with BBC 1? It may just be the specific program you are watching. Night Sound mode on the Arc or a dynamic range setting on the Sky Q might fix the issue.

Having messed around with the switch, it seems as though the issue was the ‘auto switch’ function. 

I turned that off & I was able to get the switch to work, by using the supplied remote….

The only issue now, is there is a quite large sound drop while watching BBC 1.

I’ve checked all the cables & all seems well.

Is this normal when first setting it up, or is there a setting to be changed on the Arcana?

Tried this but still nothing?

Disconnected the Arcana & plugged the Sky Q into the switch, then the out switch into the HDMI 1 ok the Sky TV & sound & picture came through fine.

So it seems the Roofull is working….‍♂️

I’m glad the Arcana is working with your Panasonic player. Does the Sky Q still play Dolby Atmos audio?

Try unplugging the Sky Q, TV, Arc, and Arcana from power for about a minute to see if it fixes your issues. Are you using the new HDMI cables for all the connections?

I would also post the question on HDFury’s Discord page and see if they can help. There might be a setting on the Arcana that can be adjusted to fix the audio delay.

I have the Sonos Arc connected to the Arcana eARC out & the HDMI out connected to the HDMI 3 eARC on the TV. 
 

Is this correct?

Try unplugging everything from power for a couple of minutes and test again.

The HDMI input on the TV is set to HDMI 3 (eARC) which is where the HDMI out from the Arcana is plugged in?

No problem. Good luck!
