Most of this audio problems are caused by bad drivers. You can check this on your PC with LatencyMon.

Thank you once more for the great tool LatencyMon. It makes a huge difference to actually see a report with measurements taken over 30 minutes.
Anyhow the problem seems totally unrelated to the Smyth Realiser A16 since LatencyMon shows problems even if I use the onboard SoundCard or the ifi nano.
I have tried to figure out which Bios settings might be helpful and also changed the Windows 10 Energy Management to High Performance.
Here is the report. Maybe someone more knowledgable than me knows what it says:

___________________________________
CONCLUSION
___________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
___________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

REPORTED HARD PAGEFAULTS
___________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: explorer.exe

Correct, but it does present itself as 7.1 capable and I didn't see anything in your question specific to Atmos.

I don't remember if Windows wraps all audio in an Atmos container when configured to use Dolby Atmos for Home Theater or not, but I would see if the problem exists when using 7.1 LPCM over HDMI and/or USB.

Thanks, but as described above it seems not a A16 specific problem.

Not sure how many A16 owners has seen the new Channel Remapping from John over at 3dsoundshop



Hello Friends...

I often get asked, as good as the 3DSoundShop PRIRs are… is there any way to squeeze any more performance/immersion out of them?

Well, after several months of tinkering… I am pleased to introduce Channel Remapping! An update to all of my existing PRIRs.

What is Channel Remapping? It is the reassignment of specific channel angles and locations to meet the exact specifications of Dolby and DTS. *

What does this do? This will take the immersion level of all rear surround channels of your listening rooms to another level... It's not subtle!

So what is included? This PRIR update will include six remapped channels, including two completely new speakers angles of ±150° for the ultimate in audio immersion... The "default" to "remapped" locations can be seen in the animated images below.

How are the remapped channels used? Click here for PDF tutorial.

How do you get this new update? It is now available in 3DSoundShop online store: https://3dsoundshop.com/store/

Purchase options are available for both single and multiple Remapped PRIRs.
As always, I'm glad to answer any questions.


Thanks so much for your support!
Happy Listening
John

Anyone try this eARC extractor https://www.amazon.com/gp/aw/d/B094PPVKFL/ref=cm_cr_arp_mb_bdcrb_top?ie=UTF8
to hook up to the A16?

My hisense tv eARC is not playing nice to give me atmos to the A16 eARC….only gives me max 5.1….the device apparently extracts atmos from an eARC source so that you can then output to any hdmi in and get up to full atmos.

I think this is the original one from Germany https://feintech.eu/products/vax01202-hdmi-earc-audio-extractor-splitter
and the above link seems to be a clone.

Looks exactly like the one I have, again another brand name, I payed US $47.25. I haven't used it anymore after my last post quoted below.
But if the TV is "not playing nice", it could be that it does the same with this eARC extractor.

I ordered this eARC audio extractor:
https://www.aliexpress.com/item/1005001928796555.html
[Edit: link doesn't work anymore.]
And the eARC audio extraction works. At least for the Dolby formats. My Samsung TV doesn't support DTS or multi channel PCM so I couldn't test that part.
I only could not get the HDMI input to work yet. (It should also be able to extract HD audio from the HDMI input so it could basically work as a HDMI audio video splitter.)

I tried again today and now I couldn't get eARC audio extraction to work anymore. The manual is pretty useless.
Probably I should power up my devices in some specific order, and have the "copy EDIT" switch in the proper setting at the proper moment.

 

[shmau]

I have successfully used the HDFury Diva as well as VRROOM with the A16. The audio out in those goes to one of the HDMI inputs, doesn't really matter which one as it includes a dummy 1080p or 720p video stream which should be supported by basically anything. Due to being a dummy stream it isn't HDCP protected either which makes it even better. Obviously much more expensive devices but they work and have a ton of flexibility.

Both devices can extract eARC audio from a TV if you want to but IMO plain old HDMI audio directly from a source is always a better option.

Doesn't look like it does HDR 10, or Dolby Vision. My C1 is working perfectly, does both HDR 10 and Dolby Vision natively and passes an ATMOS DD+ stream to the A16, which indicates newer LGs should work as intended.

For some reason, however, I can't get my NVidia Shield to pass Dolby Vision. I've tried it two ways. First NVividia ===>A16 HDMI in===>LG C1. With this method, setting won't even allow an option to make DV available. Think that Realizer won't pass DV though it does pass HDR 10.

Other option is NVIDIA====LG C1 (HDMI 3 Input)===>A16 (via eARC). Again, only HDR 10 even though menu allow the Shield to be set to pass DV.

You can fix that with one of the two HDFury devices I just posted. It'll work flawlessly though a little initial configuration may be required depending on how exactly you want to set up things.

Even though I was at the airport on the way to the Maldives for my 31st wedding anniversary, I immediately signed up for this upgrade to the full set of PRIRs that I have already from John.

Wife is very upset.

Apparently, when you've been in Maldives for six hours at the start of a romantic vacation, it's bad to say out loud that you wish you were at home to hear the new sound scape from your headphone setup.

If we end up divorced, the A16 comes with me. The kids are grown up so I don't even have to choose.

That only plays a role when you use the hdmi input of the extractor. When used purely as eARC audio extractor it doesn't need to do anything with video! If I remember correctly it just outputs a 720p or 1080p black image via the "audio only" hdmi output together with the audio it receives from the TV via eARC, there is no video going from the tv to the extractor.

So, from those quotes, it looks like it did not work as advertised.

 

[sander99]

Well, it did work at the beginning, and maybe I would have got it working again with some effort but I was lazy and I changed my setup such that I didn't need it anymore. And in my case it would never have been a 100% satisfying solution anyway, because my Samsung tv doesn't support DTS via eARC (and that is not the fault of the extractor, but Samsungs decision).
One thing is for sure: the user manual of the extractor doesn't help much.
I would agree it is a gamble to buy it, especially in your case where maybe the tv is the problem.

I suspect this may have more to do with the particular streaming service and its app that you're trying to make use of on the Shield, rather than the Shield itself being the problem.

For example, my experience is that Hulu app running on bth the Shield as well as ATV4K does NOT provide Dolby Vision. In contrast the same content IS available in Dolby Vision when delivered via the Hulu app running on Roku Ultra.

So what are the specifics of the attempts you're making, and which are failing? What streaming service sources, and what specific content getting only HDR or nothing, that you feel should be in Dolby Vision?

Other than this Hulu situation I've had no problem delivering Dolby Vision content from apps running on any of my own three streaming devices THROUGH the A16 and on to my LG C9, either (a) directly from HDMI-out of the A16 to HDMI2-in of the C9, or (b) indirectly from HDMI-out of the A16 to HDMI3-in of my Yamaha RX-A1080 AVR and then from HDMI1-out of the AVR to HDMI2-in of the A16. In other words video is sent from A16 to the C9, or from A16 through AVR and then to the C9.

There are additional differences from streaming app to streaming app, and between the three streaming devices, regarding "refresh rate" of content displayed on the TV, and whether or not arriving 23.976/24.000 framerate content is delivered and played by the TV at the "matching refresh rate" or whether it is delivered at 60hz (i.e. 59.94). Again this is app-specific and may differ by streaming device as well. Also, is it possible to obtain a "match refresh rate", either automatically through a built-in streaming device feature setting (as works correctly on the ATV4K) or through optional software (e.g. through the Refresh Rate add-on app for the Shield, which unfortunately doesn't work any longer with Netflix ever since the recent upgrade to Android 11 and Experience 9 but still works with other apps).

It's a real nightmare, with multiple apps and multiple streaming devices. But since no one device seems to work perfectly for all streaming sources, that's why I've invested in "one of each device" so that I can hopefully find the particular one or more delivery methods that gives me DV+DA if possible.

-> I can confirm that I get Dolby Vision on the TV for apps on the Shield running through A16, except for Hulu. I get DV/HDR content passed through the A16 to the C9 TV (when available for specific content) using Netflix, Prime Video, HBO Max and Showtime Anytime.

There is a new post at the facebook page of av-in.com:

“Auro 3D is coming (very soon) to the SMYTH Realiser A16, and that changes everything. Get ready for a second audio slap! Not just for the 3 (sorry, 4...) Auro 3D discs that are dueling, but for the Auro Matic upmix associated with it. You've never heard your Dolby/DTS 5.1 mixes like this, rendered in 7.1.4. The A16 is already doing wonders in immersion with headphones with all audio tracks up to Dolby Atmos/DTS:X, but here we are taking another step. On all soundtracks: films, series, music, games... Your headphones and your ears will heat up: you'll want to rediscover everything!” (by google translate)

That's pretty huge. If they enable Dirac Live at some point (it has been said that the hardware is capable, though I'm not certain), then it would basically be good as an actual surround processor too.
