Title: What settings for DTS/DTS-HD HDMI ARC
Post by: Wungun on January 12, 2025, 08:12:28 pm
Tried a number of settings... Bit streaming settings, etc...
MC won't out put DTS or DTS-HD to my receiver.
I feel like I'm missing something

If you have DSP Studio > Output Format > Output Encoding set to anything else other than None, try setting it to None.

DSP studio? Is this 'DSP and Output format' in V31?
Set to 'none', it outputs PCM to the receiver... So no surround at all.

Use Google to search for JRiver DTS.

You need to use bitstreaming and no conversion in MC.

I am using bitstreaming option, HDMI and I've tried individual or just single options all with the same result.
Where in MC would it be doing any conversion?
Do you mean the JRSS mixing? It's off... Set to no up or down mixing.
If you mean output encoding, I've tried the Dolby one and 'none'
When I use none, it outputs a PCM audio stream

If you are bitstreaming then it won't output pcm so that must mean you are not actually bitstreaming. What does audio path say?

This is looking like it might be an nvidia driver issue..? Supported audio formats in the sound properties no longer shows DTS-HD, just DD DD+ 🤷

Okay, so I figured out the issue... And I'll explain, just in case anyone else finds this thread.

So I was trying to get Atmos, DTS-HD and TrueHD from my PC (Quadro P4000) to my receiver (which isn't 4K HDR but 4K 60p).

My 1st configuration was HDMI👉🏻TV👉🏻HDMI ARC👉🏻Receiver which works for Dolby Digital and the like... But not anything lossless.
Reason being, with the Quadro connected to the TV, the ONLY audio options available are 2 channel 48Khz Dolby Digital and Digital+. This is because the TV is only a stereo device!

For whatever reason, nVidia doesn't display all the audio format (thru HDMI) options... Only the options on the CONNECTED device.

When connected directly to the receiver, all audio formats that the Quadro supports are shown, DD, DD+, TrueHD, DTS, DTS-HD, and all the sampling rates!

Solutions...? Quadro👉🏻TV directly for HDR video (TV volume off)
A second HDMI👉🏻AV receiver.

The real trick is, you need to have both DISPLAYS enabled on the PC, configured as 'extend displays'
This is the only way I've been able to keep HDR thru windows and allow the audio output to the receiver to work.

Now I just configure MC using the audio from the receiver, enable bitstreaming and Bob's your uncle!
