With this you will be able to bitstream, thus not losing Atmos or other codecs. Edit: I'm actually sorry this resurfaces so constantly, more than writing the guide I don't know what I could do... Last edited by ashlar42; 6th June 2017 at 13:39. |

You are correct. Which is why I linked my guide. Furthermore, I'm not sure if you could support full Atmos decoding in any case. I've always seen PCM output max out at 7.1. Whereas regular Atmos configurations can offer 7.1.4 channels. I'm not sure "normal" PCM output from PCs can carry 12 channels.

Well, I don't think it would be possible to transport such a PCM stream over HDMI, but analog output would be possible, assuming the hardware exists (it most likely doesn't). After all, as far as the Windows audio APIs are concerned this is at least theoretically possible. The software doing the decoding would have to ask the user for information about speaker layout in order to properly decode the "audio objects" and map them to channels.
Of course none of this is ever going to happen - people having more than 5.1 speakers is already a niche market, and people wanting to use a PC instead of an AVR to decode such >7.1 streams is an even smaller niche market still. But one can always dream. |

HDMI 2.0 claims 32 audio channel support, but I don't think they mean uncompressed PCM channels because the audio bandwidth didn't actually increase. So yeah the only way to get 12 channels output would be a DAC directly connected to a PC, either a soundcard or perhaps a USB DAC(although 12 channels USB DACs get expensive, mine is only 10 analog outs)

My CPU its only at 10%, and my gpu 23%, and I'm playing a full remux bluray with HD audio. Here are the madvr stats: Do you think if I upgrade to the gtx 1070 I will get rid of this problem? I have an i5 cpu. Thanks! |

I would however like to do it your way so I cant go back to bitstream in JR so my Atmos plays correctly, but your setup looks so complicated to setup. Ive read it a number of times but i think its beyond my knowledge |

I think I've said something to you before, but you really need to learn more about what madVR does by actually looking at the results rather than asking all the time.. Last edited by ryrynz; 7th June 2017 at 04:14. |

Follow through the guide is painful. In my case my avr is too old for HDR passthrough so I run a separate HDMI for audio only, which saved me some time for the audio block part of the guide. Here is the way I obtained my "perfect" refresh rate base on that guide. 1. set 1080p23/ 2160p23 in Madvr and start a 23.768 video 2. check the OSD to see the refresh rate is running faster or slower then 23.768 3. Go to Pixel Clock Calculator (PCC) and try the settings with (+xxxxHz)"to compensate the slower refresh rate" or (-xxxxHz) "to compensate the faster refresh rate" in Custom Resolution Utility (CRU) 4. If have difficulty to achieve 23.768, try 47.952 Hz instead 5. Work until you see the "no frame drops or repeats ever" in the OSD |

Just set 1080p25, 1080p30, 2160p25, 2160p30 in Madvr and use Video clock in Jriver and you are good to go. |

Ok thats fine but when you play an Atmos film you have to go back to bitstream as it wont play as true Atmos in PCM. Going back to bitstream for the Atmos films you loose the clock in JR again. There is no easy way to hold the sync perfectly using clock when you want to play an Atmos film natively using the clock in JR.

Do you think if I change the 660 for a 1070 my problem will be solved? Thanks! |

Honestly, I'd just start with a clean config. Grab MPC-HC/BE use LAV or internal filters, back up your madVR settings and reset to default, disable ffdshow, disable reclock and see what happens.
If still getting stuttering, uninstall your graphics drivers completely, reboot and reinstall. |
