PC decoding Dolby ThrueHD / Atmos and DTS-HD MA / DTS:X down to 7.1 soundcard analog output

Hello everyone,

I am new to this forum, so please excuse me if I ask things that were already debated.

I would like to have my PC decoding as a pre/proc for all the audio/video formats and output the analog sound signals of the 7.1 soundcard to a 8 multichanel amplifier (connected to 8 passive speakers), and the video directly to a TV.

The video part is quite clear. The HDMI of the video card will output to the HDMI input of the TV. The sound however seems to be a tricky part.

I found a few ideas, but I am not sure to what extent the results are similar to having an all decoders enabled AVR for the sound part (for the already regular solution of connecting the HDMI of the PC to the HDMI of the receiver and the HDMI of the receiver to the HDMI of the TV, and the speakers to the receiver).

Do you have a tested working solution? Maybe something like K-lite codec would do this... I would like to know if all the formats (Dolby ThrueHD / Atmos and DTS-HD MA / DTS:X) work correctly, not emulated/simulated or something like this. If you think you found a solution, how could you test Dolby Atmos / DTS:X in 5.1.2, to be sure that you don't only get Dolby ThrueHD / DTS-HD MA in 5.1/7.1?

Did anyone tried the solution for both 4K BD and MKVs?

I would also like to have a 4K BD drive in my PC, and have all the audio/video content played as with a dedicated 4K BD player. Is it possible?

Thank you,
Gabriel

Set your speaker configuration in Windows to 7.1.
In codec pack installer also select 7.1 or "same as input".

All those audio formats are supported for decoding. The only exception is Atmos. In that case the TrueHD part is decoded and the Atmos extension is ignored. When bitstreaming to a receiver, Atmos is supported.

I don't know if there is any commercial BD players that support decoding of Atmos. Most likely they only support bitstreaming.

Thank you for your quick answer.

I will assume that for DTS:X is the same case as for Atmos.

What do you anticipate to be a time limit for introduction of Atmos/DTS:X decoding in the PC world?

Thank you,
Gabriel

Yes, same for DTS:X.

It is very unlikely that PC decoding will be possible in near future, or ever at all. Also because the decoding process is different:
