I’ve just noticed that I can make the issue go away if on the Sony TV I set the eARC mode to off (instead of auto). According to the MusicCast application this results in Dolby Atmos/Dolby Digital Plus stream being send (for a track in Dolby Atmos). While if I set the eARC mode to Auto then it reports Dolby Atmos/PCM. I understand this is loseless but this introduces the 2s-6s delays when switching tracks, etc.Not really, the basic set up was really easy - no surprises, etc.
I haven't got time yet to spend quality time with it, but the first impression is very good.
One unexpected behaviour is that I have blue ray player and apple tv connected directly to TV and then the a6a is connected over hdmi/eARC - it works so far very well, but each time it gets new audio signal (skipping to next chapter on blueray or new song on ATV/Music, etc. ) the first 2s-6s there is no sound. IF I switch audio to tv speakers it doesn't happen - it only happens with hdmi/eARC + a6a. Not sure if the issue is with the tv/earc or the a6a. I submitted a case with yamaha support earlier today.

eARC isn't required to convey DD+ even if inclusive of Atmos metadata. You can access DD+ inclusive of Atmos usiung just conventional ARC.
What you'd lose is the ability to pass HD formatted audio such as TrueHD through the TV or multichannel PCM.
Conventional ARC is limited to SD 5.1 formats, DD+ with or without Atmos metadata or just 2 channels of PCM.
Dolby Atmos would only ever be sent in conjunction with multichannel PCM if using an external device connected to one of the TV's HDMI inputs that relies upon Dolby MAT for output of Atmos. Such devices would be an XBOx, Windows PCs or the Apple TV 4K. If connecting any of these directly to the TV then you'd need eARC in order to passthrough Atmos in conjunction with multichannel PCM using Dolby MAT.
thanks I will test this over the weekend so if i have simliarNot really, the basic set up was really easy - no surprises, etc.

Why connect the ATV and the UHD disc player directly to the TV? There's no real reason to do this and you could simply connect them directly to the AVR.
Connect the ATV and your UHD disc player directly to the AV receiver as opposed to passing their associated audio through the TV and out via eARC.
I know I could and I will try it.
HDMI/eARC is a little bit more convinient though as I can still use the devices without using AVR if for some reason I would want to. Also currently by talking to homepod/siri I can turn off or on the TV (it does talk to ATV which then "talks" to the TV) - not sure if it will still work if I connect it to the AVR directly - I will have to test it.
I haven't really made my mind yet which way I prefer it nor I had time to test connecting it directly yet.
I didn't know that - thank you!Just ensure the HDMI passthrough in standby feature (HDMI STANDBY THROUGH) is engaged on the AV receiver and you'd then still be able to utilise those devices connected to it via HDMI while the AV receiver is in standby.

Can you still change the inputs for the sound when it’s in standby ? My rx-3900 would only do this on the last input selected. I would love to be able to change the inputs when the amp is in standby so you can select different devices to pass the audio through. Can this be done on the a6a and a8a. Thanks.Just ensure the HDMI passthrough in standby feature (HDMI STANDBY THROUGH) is engaged on the AV receiver and you'd then still be able to utilise those devices connected to it via HDMI while the AV receiver is in standby.
Can anyone confirm this yet? Or is everyone still waiting for the firmware upgrade?Also note that only 3 of the inputs on the V6 and the A2 will be 4K 120Hz enabled and they will also be capped at 24Gbps. The A4 and the 2 models above it all include 7 inputs that will be 4K 120Hz compliant and they'll all handle 40Gbps.
tried to test this setup however eARC to TV isnt a function i have yet on my TV (Q950R) eARC firmware comes out this month (at last) lolNot really, the basic set up was really easy - no surprises, etc.

I'm looking to upgrade an aging Onkyo 626 and have been waiting for proper HDMI2.1 support for over a year. Reading lots of conflicting reports on whether the A4A will be able to handle 40Gbps uncompressed 4k120, on all ports. Yamaha's comms have suggested it will, but after it came to light that the A2A is only 24gbps and not on all ports i'm cautious - and that was only after a hardware mod.
The Surround: AI mode on the A4A receivers+ sounds interesting, anyone else demoed it? Sounds worth the $$$ difference over the A2A alone.
The Ai mode is nothing new and was included onboard previous Yamaha models. I'd tend to suggest turning it off and this is in fact exactlyt what I do with my current A1080..
What Is Surround:AI™? - Yamaha Music - Blog
Learn how a Surround:AI surround sound system works, and how it enhances the movie watching experience in a home theater.hub.yamaha.com
I'd also suggest that you'll never really want to apply the DSP modes to discrete multichannel sources and are far more likely to portray such sources as they were intended to be heard. I on;y ever apply DSP to TV content.
I'd say Ai is interesting, but not a must have or something you cannot do withput. Who really wants somone or something messing about with the way the audio sounds on a scene by scene basis? Besides which, who's determined this to be artificial intelleligence? It simply applies pre formulated algorithms that then set the output as someone who works at Yamaha has determined it should be set. The person at Yamaha could theoretically be deaf?

I'll have to check, cant say I've noticed, when i switch from say PC input (HDMI 4) to Xbox input (HDMI 3) I have a 2s delay while it switches usually to from one format to the other usually surround to ATMOS.Actually it is not eARC itself causing the issue.
As per my other update it also happens when I connect ATV directly to A6A.
However I've noticed that the amount of delay/silence depends on a program in use when switching from PCM to Dolby Atmos/PCM. In STRAIGHT program it is about 2s (still noticeable). In SURROUND DECODE Auto it is about 6s. While in SURROUND: AI it is about 2s. The Hall in Munich is 2s as well.
Do you see the same?

Sadly I dont think I'm going to be able to test the exact issue as i dont use eARC and my streaming device is a Nvidia Shield Pro 2019It's not switching between sources (I haven't tested it) - if you have ATV all you need to do is to play music via the Music app which is Dolby Atmos - A6A reports it as Dolby Atmost/PCM. Then skip to a next track which is is just PCM and then back (or next) to Dolby Atmost/PCM - and depending on mode (straight, etc.) I always see either ~2s or ~6s period when ATV plays music but A6A doesn't output any sound. IIRC same happens if you skip from one Dolby Atmos/PCM track to another Dolby Atmos/PCM track. If you let a song to play to the end and then it starts playing next track automatically - the issue doesn't happen. Or if in a middle of a song you go back to the beginning - the issue doesn't happen either. While this might suggests it is ATV issue, I don't think this is the case given that the delay depends on mode (stright vs. using DSP).
I also observed the issue when playing some BluRay discs and skipping to next/prev chapters - for about 6s no sound is outputed from a6a each time I move fwd/back to another chapter (with dsp mode). This was when the player was connected to TV and eARC was enabled between TV and A6A. If I disable eARC (and use just ARC) then all works fine (although in this case A6A recognizes it as DA/DD+ iirc vs. DA/PCM).
So if you have ATV you should be able to easily reproduce it via the Music app.
There is nothing conflicting about it. There are no "reports" and it's a pure speculation based on last year's fiasco with 2020 models of receivers from Yamaha and Sound United.Reading lots of conflicting reports on whether the A4A will be able to handle 40Gbps uncompressed 4k120, on all ports.
It's interesting how consumers are still willing to take risks and purchase AVRs that are not fully functioning out of the box. Fingers crossed it all works well, but I'd be very, very cautious about new devices and not purchase it until proven to be fully operrational in HDMI 2.1 department.
