ALSA .. Pulse ....settings?

Wow, what a feature-rich piece of software ..

I took your advice and came up with this. Puzzling. I have no idea where "32-bit" came from; the codec is 24-bit. Plus the DTS-HD MA is 7.1. On the positive side, the path is "direct."

So there are extra bits and two missing channels. Any ideas what is happening?

So my understanding is that you can't use volume control or DSP with bitstreaming (I actually thought the bitstreaming option automatically disabled them?), but your screenshot shows that you're using internal volume so some setting somewhere isn't working as expected.  I assume your current bitstreaming setting under the audio options is "HDMI"?  As an experiment, try changing the bitstreaming setting to "Custom" and check all the boxes that your output device supports, then start playback and look at the audio path and see if that changes anything.

If that doesn't change anything, then, as an experiment, try going into audio settings and disabling volume control (Volume Mode:Disabled).  Then open the "DSP & output format" sub-menu from the audio options menu.  In the DSP & Output format menu try unchecking *all* the boxes (including output format!).  Then, with those settings in place, try playing something and see what audio path says.

If that doesn't make a difference, I'm at a loss, but report back and maybe someone else will have some ideas!

I returned MC’s device to ALSA HDMI DEV=0 something or other. Select Disable Volume. Watched a movie with 7.1 DTS-HD MA. Prepro still reports 7.1 PCM. With that input my prepro has limited modes available to select. I selected Direct.

The JRiver apps shows 0 for output volume, but I could tell that the volume was maxed as I needed to turn down my prepro.

Audio Path now reports 48KHz 64bits 8-channel.

I will try the DSP & Output settings you suggest but I am not optimistic. With my prepro receiving PCM the modes I can select are limited. I will say that The Bourne Legacy sounded as good as ever, maybe a bit better.

My next move is to image the Debian installation, wipe the SSD, install Windows and try MC. If that allows me to properly bitstream the codecs to my prepro, that’s will be my path forward. Regrettably, Windows of course will be a huge PITA .. overkill for a simple MC server and clients.

Edited: Sorry for the grousing. If I get the operation I need in Windows I will be back to work on getting it to work in Debian. Thanks for your help!

I am back with more data. To recap, I am using a 4th generation embedded i3 with Intel HD Graphics 4400. I tried another media player in Debian and played a 7.1 DTS-HD MA movie file directly. I was never able to pass the native codec to my pre/pro; 7.1 PCM is what it listed as incoming. I was going to install and try VLC but decided to install Win 10 and MC next. With that combo I could pass the 7.1 DTS-HD MA to my pre/pro. So it can be done with the hardware I have.

I really do not want to use Windows for Media Center/Library Server. What the heck do I need to do to get MC/Debian to pass the codecs? Is it a Linux driver issue perhaps?

Did some querying the dev group on this.
Only DSD bitstreaming is implemented on Linux at this time.

Until we get time to do that on Linux, I'm going to remove those options.
