Need advice on HDMI to PCM decoding
Bob4K:
Of course.
Dune Solo 8K: quite better than the previous models, its picture quality is now as good as the reference Oppo 203. The red push, especially when you convert SDR to HDR is gone now, colors are neutral.
Goldmund 16.8: annoying with some decoding quirks when sourcing from a non blu-ray player, but with its 2 channel PCM outputs and floating point processing allowing phase an frequency correction, just the best by a wide margin to drive amps with included DACS, bypassing every thing analog up to the last power output stage to the speakers.
And while I'm at it, Envy Extreme processor, and Barco Freya+.
jctcom:
So forgetting the splitter for now.
You are trying to go from the Dune to the Goldmund then from the Goldmund 1. to a video display and 2. to an AMP / receiver or something like that?
The main issue is that the Godmund does not decode digital codecs (DTS-HD, Dolby TruHD)? But maybe is does decode the lossy ones (I think you mentioned somewhere that it displayed Dolby Digital and DTS?)
So are the 8 RCA Outs on that to combine to make an analog 7.1 capability?
You are using this setup for both movies and music?
Carl.

The Goldmund is the AMP receiver.

Yes it does, but there is a weird handshaking problem that prevents it from doing so from the Dune, but not from an Oppo.
And if there is the same problem with the JRM based splitter that I would like to build, then JRM can do the decoding.

These are 8 SPDIF RCA outputs, and each of the 16 channels can be assigned to anything you want, each channel with several specific phase and frequency filters.
That's done by the reseller, with measuring tools, not by hear. Hearing comes at last, but only to optimize a little bit.

Oh yes!
mattkhan:
personally I wouldn't do this using MC as MC's TV module is quite limited in my experience vs MPC-BE or MPC-HC, I can say that using the latter with any of hte magewell cards or usb devices works fine with an appropriate splitter in front to strip HDCP. Using one of their pcie cards will give sufficient bandwidth to handle 4k60 input (I have this one https://www.magewell.com/products/pro-capture-hdmi-4k-plus), if you only need 4k24 then any of the USB ones are fine. Either of these come up quite cheaply on ebay quite regularly. I've tried 3-4 cards with MC and none of them worked at all well hence why I'd say don't use it unless you can find someone who can positively affirm that a specific card works well.

You have tried a different HDMI Cable? A higher end cable can make a big difference as to what makes it through the handshaking. I use 8K rated cables on all my system even though my TV is only 4K.

Normally SPDIF cannot carry lossless Multi-Channel Signals (DTS-HD, TrueHD). This may be different this case since I also don't think normal SPDIF can carry 16 Channels.
I guess it's possible that Goldmund has created their own protocol or something?
In any case I am off to bed (after 2am here). Will be interested to see how this thread progresses in the morning.
