Lightbulb WARNING! Newer Nvidia drivers broken - no support for Dolby Atmos / TrueHD / DTS MA

This post relates to issues when bitstreaming from HTPC via HDMI to an AV Reciever with an Nvidia GPU handling the audio via HDMI.
Nvidia driver later than 355.60 does not work (at least up to 368.22 where I had issues, but likely also after that)


Previously this year both Dolby TrueHD and DTS HD had been working for me.
After that a windows driver update was installaed by windows update for my Gefore GTX550 and I did not really notice any issues, but then I mostly watch std DD and DTS movies and dont look to much on my AVR display


Yesterday I was going for Atmos to see if that worked and noticed that DTS HD was seen by my AVR as std DTS
and DTS HD gave an error prompt in MPCHC that it couldnt recoginze the audio format.
Hence i uninstalled MPCHC, LAV filters and installed the latest version. No progress.
Tried resetting MPCHC and LAV and redoing the setup, but same issue.
Started doubting myself and googled for hours on issues with Atmos, be it MPCHC, non compliant GPU, LAV filters or any other issues.


After spending allmost 10 hours I found BELOW post on an Nvidia forum. The guy has experienced the same thing and was right on the money with the solution but Nvidia did not want to recognize the issue, You can read the 3 pages where this guy even struggles with forum members which I dont understand since he was really just looking for answers and was way more knowledgeble than many of the repliers. Anyway.

- I look at my driver version and saw that I had version 368.22 installed for my GTX 560 (nvidia package version). Poster above had a GTX960 so it does not seem related to a single card.
There was also another poster with the same issue but with GT740 under Windows 8.1 and 980TI under Windows 10.
- According to above poster, he had found that the last driver that allowed TrueHD and DTS-HD to work was version 355.60 (but he had other issues with displaying 4K with that driver)


2 resolutions to the issue were mentioned in the thread.
- Nvidias solution (after a lot of support talk and Nvidia even askin poster to contact Microsoft for the issue ) was to slightly lower the resolution of the display and that would enable TrueHD and Atmost once again. For this guy it seemed to do the trick, but who wants to turn down resolution for the display really?
For me, it didnt matter if I went all the way down to 720p 30Hz - audio formats were still broken.


- So I made a quick test according to posters proposal and rolled back video driver from device manager. That did not help.
Then I rolled back the High definition audio driver and BAM - suddenly the DTS-HD and Dolby True HD encoded formats re-appeared under "Playback devices - tab playback - my reciever - tab supported formats" as in attached image. Also Atmos worked like a charm


I then updated my Nvidia driver package to 355.60 which the poster above found to be the latest working one and the audio was still working as it should (also 3D H-SBS H-OU was working)




I hope that this will help somebody, it sure helped me after a sleepless night.


Kudos to "altoiddealer" who found this (in my opinion) hard to find bug which falls back on Nvidia

Has this issue been resolved after recent updates? There has been several driver updates since your last update. Thank you for all your work in regard to this matter.

Thumbs down

I just put together a new rig with a GTX 1060 (running W10). Installed the latest drivers and no HD audio formats are recognized in my audio settings (see OP for screenshots). I also have an older machine where i experienced this issue with a GTX 560 ti (running W7). If I do any driver update on the W7+GTX 560 ti machine, the HD audio formats disappear. Since the 560 is an older card I was easily able to go back to older driver package. However, being the 10 series cards are "new", you cannot go back to any driver pack that is 355.60.

This is definitely a nvidia driver issue and they need to get their sh*t together. This has been an issue since mid-2015 and it is almost 2017. nvidia still will not admit there is an issue here.

Furthermore I tried doing the "lower your resolution trick and the HD formats magically re-appear". This does not work and I fail to recognize how in the world resolution would break audio codec recognition. If that is the case, that would mean the GPU driver is the culprit and the HD Audio drivers are not to blame. It means the newer GPU drivers are breaking the HD audio driver from working correctly.

Had I known this was a driver issue, I would have bought a 900 series card, as they are compatible with older driver packs and provide 4K resolution. I am totally bummed and pissed nvidia won't provide a resolution to this 1.5yr+ old issue.

Who's ready for some AMD instead?

Are you guys certain of this? I'd be interested to see screen shots of your audio panels along with your graphics properties window to see what driver pack your running as well as to see that you guys actually have DTSHD MA and TRUEHD showing up.

I have a 1070 so I'm definitely not running old drivers. Since the hardware is new, I was updating almost every time NVidia put out a new driver. I've since rethought that. First, they put out way too many releases (game ready release for some game I'll never own, whoopdeedoo). Second, there have been regressions periodically. I believe there is a memory clockspeed issue with the current release.

Even if the drivers are good, it's just not worth the hassle. Inevitably, something gets out of whack and the HDMI audio devices gets renamed or put back to stereo. Sometimes it takes a sleep or reboot or some random combination of the two. I doubt NVidia cares much about the HTPC...not their bread and butter. I had AMD before and they're definitely no Utopia. At least they have better sample rate support.

Ran into this too... 355.60 for life on my HTPC, disabled all updates for Nvidia...and Windows updates (keeps a steady working PC stable, updates can break things or cause performance issues)


Unless someone can prove that a newer build is as stable as 355.60... As I would like to use this PC (htpc) on my 65" tv for a little gaming and new games need new drivers.

Solution improvement

I specially created an account in this forum to help people with the same problem We have January 2020, and as you can see some people still have this problem. I have a Geforce GTX 560 Ti (if you don't play games, it's still great) and Yamaha RV-A3030. I looked through dozens of forums and no clue helped. Only a tip from this forum did the trick. After installing the 355.60 drivers, HD Audio appeared in HDMI. The problem is that these (video) drivers are very old and have a lot of bugs. So I came up with the following idea: 1 - I downloaded both the 355.60 drivers (supposedly the last where HD audio works) and the latest (currently 391.35). 2 - I unpacked both (the installer can be started, the files will be unpacked and you can close it). 3 - I have put old HD audio drivers in the unpacked latest drivers (you just need to overwrite the "HDAudio" folder). 4 - I installed such crafted drivers and everything works. I have HD Audio (DTS-HD and Dolby TrueHD) and the latest graphic drivers at the same time.
