Ive emailed Orei which makes a couple of extractors with hdmi audio out to ask and I'll post the results here if they reply. Based on the current specs they have listed it technically could output dolby atmos as well but it doesn't specifically state so. Not gonna link it cause I realized I got sent on alot of dead ends during the research to outdated products and this one isn't verified suitable yet.

Windows already can output atmos via hdmi (via dolby access app) so now it's just up to Nvidia to just do some programming wizardry to make its hdmi output transmit audio that is compatible with the sonos EARC hdmi input. One can only hope /fingers crossed.

Well, a PC is never going to output atmos on an ARC channel, as the ARC channel is something that is between the display and the audio device, not the source. The critical elements here are a display that supports earc (rare) and a computer than can output ALL audio as truehd, not just pass a truehd track through.

I'm curious why aren't more people interested in this device? Its about 100usd (with shipping) and seems like it can extract/embed dolby truehd arc signals (silent about atmos). I've email SCT to ask about atmos and whether it's EARC compatible.

it looks really cool! i pinged them on the avforum and they said it will work for hdmi sources from the PC.

sadly i just bought a creative ae-7 for DDL 5.1 via toslink. not sure if i wanna spend another 150usd just yet for the arcana. will wait for post-launch reviews.

Comes in different models, the Creative Stage series of speakers are designed to blend perfectly into any room setting with their slim profile, and will easily fit inconspicuously under TVs, ultrawide monitors, and computers.

We put our engineering chops to the test by integrating high-performing drivers that are specially tuned for loud, powerful, and immersive audio that will breathe life into your music, movies, and even games.

I have the same problem. Worked fine with a 1080ti. RX 6900 xt won't let me activate Dolby Atmos. Error message... This is definitely a problem caused by the AMD HDMI Audio Driver. The card is good, but this is really bad and needs to be fixed soon.

For it to work, your soundbar needs not just HDMI input it also needs AC3 decoding hardware.. many soundbars only accept PCM but might falsely advertise 19-21 discrete speaker channels with height/ceilingspeakers from a 9.1 channel bluray disc. Yes it creates additional channels with the dolby atmos 5.1.2 or higher surround sound speaker system. So your soundbar advertising ceiling and height speakers and UP TO 19-21 speakers in different positions in your room is the most max lvl 'special tech guy' thing i've seen in minutes. many Tv's like samsung you put the receiver or soundbars ARC channel port a specific one in the back and connect that one cable to the TV.. the TV has to go in the ARC port too, and be configured in the TV sound menu to output via ARC or enable it. its maybe not in the sound menu but possibly needs HDMI CEC and other things or under external devices? but then the TV needs a cable to the PC or media player bluray player or whatever but your TV maybe works as a hub so you can input several HDMI to the TV and they can all sort of come out the ARC maybe.. ARC maybe isnt as great for playing back broadcast TV content or maybe the netflix app in your TV as depending on the TV it maybe sounds better when outputting to the receiver or soundbar via optical spdif toslink. remember the AC3 format same one as the 90s dolby ac3.. is just increased bitrate and channel count for 7.1 netflix DDplus and increased to lossless for DD master! its an AC3 file u must specify the SPDIF output on your PC and mediaplayer software and consider the output khz some can only do 48khz not 96. optical or some HDMI content in PCM might only do stereo for reasons bandwidth or 'unknown' causes.. i have no clue.

I have reported this problem to AMD technical support and requested they consider this in a driver update. If they come back with anything else or I somehow stumble across a solution I will update here so I will keep this open until they get back to me.

AMD support got back to me today. Their suggestion unfortunately did not work. This involved using show or hide to stop windows 10 auto updates, uninstalling AMD drivers in safe mode using the DDU tool, then installing the latest driver back in normal mode.

Hi

I have tow questions

1) HTMI cable comes from GPU and connect to sound bar HTMI_in port. so why we need TV? and what I did wrong? did I use HTMI_out port?

2) my big issue is that GPU recognizes Soundbar as a monitor and then happens many weird things. how can I fix it?

I have the Power Color Red Devil and a Asus reference 6900xt. They both had the same issue. The nvidia GPU always seemed to allow Dolby Atmos to be enabled without any issue before and after I solved this.

also the TV might be set to PCM or using optical.. optical cables are STEREO cables.. the dolby 5.1 compresses to use 5.1 over STEREO optical which is low bitrate 640kbit/s. via recent HDMI cables you can use dolby digital plus (7.1 with higher compression for web streaming like netflix) ATMOS is for 9 to 13 channel audio like bluray discs or 4k ones to be played back on your ATMOS receiver in 19 to 21 channels with ALL the height speaker channels working due to hardware atmos chip for more surrent atmospheric audio.

but the problem is DOLBY ATMOS is games is largely completely faked and what they mean is they AC3 encode their stereo audio output so if you've purchased the windows 10 appstore dolby atmos for headphones it might sound good? Or it just outputs in 7.1 or something lame with the PASSTHROUGH method or maybe even a re-encoding to AC3 as its output but its not a AC3 source file with lossless or master quality in 9-13 channels for "TRUE HOME THEATER" as in same number of speakers as the cinema theater. so seeing stupid **bleep** like dolbyvision on your cheap OLED mobilephone that has maybe 700nits HDR is probably bull**bleep** as dolbyvision is 10,000NITS HDR DAYLIGHT specced so why the worst spec and lowest quality cheapest displays on market put fake dolbyvision badge pretend to be 12bit display panels (your eyes only ever see in 300million colours and 10bit panels are 1.2billion) but colourspace RGB44412BIT (64bitRGB or 128bit) is separate to the pixels on your TVs physical panel which is ONLY EVER 10bit max as its overkill but oled is like mixing paints so they pretend its all the colours of the universe and pretend its 12bit.. sorta a marketing gimmick. Well anyways point is lots of stereo soundbars claim to have 21 speaker channel and height channel surround sound bounce off the ceiling audio called DOLBYATMOS.. but they're stereo for crying out loud.. what they mean is they accept HDMI and maybe support AC3 decoding in the amplification unit of the device.. its a crime for them to fake label things with dolby ATMOS and put dolby ATMOS logos on all the games ever when its super duper NOT dolby atmos.. i can tell by the terrible audio quality often.

but yeah ARC is done by TV's and receivers.. you dont use your TV and tune in to broadcast television channel on your TV and play the audio from the TV output via HDMI into your graphics card to capture it.. its meant for the TV to output to a receiver and have the one cable go to the receiver for your PC in the receiver to play to the TV via the AV receiver HDMI input but the TV or bluray player connected to the TV can play back to the receiver via the one HDMI cables into the receivers OUTPUT. but ARC is 5.1 is HDMI 2.0B but EARC is 7.1 support and works with HDMI 2.1 but both the cables and the TV and the receiver MUST be HDMI 2.1 in this way several devices go to the receiver to play audio via speakers with much less HDMI cables needing to be purchased and easily play audio from the TV without needing to switch input sources and so on.

ok,

1) I am using sound bar for the PC, not for TV. how can I connect it to GPU with HDMI port? is it possible to tell the GPU this device is audio and not recognize it as a display

2) my motherboard (msi x570 carbon wifi) has optical port (SPDIF) ofc soundbar also has TV optical port, but I cant connect it with optical port. Device manager cannt recoginze soundbar with optical port. does SPDIF optical port compatiable with TV optical?
