No Audio Passthrough on New "glorius" app?

[Schebberle 0]

Hi there.
I just wanted to setup a new Windows Device for my TV to watch Movies there with Emby.
Since the old Emby Theater is no more available i had to install the UWP app from the windows store.

With this app i cannot get audio passtrough to work.

i Still have my old device, and other devices, with the old "installable" windows version of emby Theater. In the Old app i have under audio options checkboxes which formats my end-device (AV-Receiver) supports. and if i playback with This app, it will Bitstream the audio directly to my AV-Receiver.

with the new App version of Emby Theater i can only change the speaker layout. like stereo/5.1/7.1 etc. no option of codecs my setup can directly decode.

So. with the old "Windows installer app" i can get my audio codec passtrough to my AV, with the new i can't. of course i tried all the settings in the new app like discrete audio and/or changing the channel setup. This is a real downgrade for me. - I even Tried this on a device which had still the old version installed. it worked there, and it didn't on the new. best i could get on the new is "5.1 PCM" 

So my main question is here: am i Missing something? is there really no way to get bitstream audio on the new app?

HI, how have you configured the audio settings in both the app and in windows?

If you need any more/other settings to check, let me know

Just look a little further down:

well this doesn't show up. see my screenshot. scrolled all to the bottom:

Also in the sound settings the formats are listed als compatible on this audio device: (yes. dolby atmos also, if i scroll down)

 

And now the audio settings screen from the Old Emby Theater, on the same device, with fully working bitstream audio it's even working flawless without the exclusive audio mode:

I see that there's a flaw in the detection (the old Emby Theater just always shows you the pass-through options, even when it's an analog output).

 

As a workaround, can you pleae click on "Umbenennen" and rename it to "MEC-O-3-H HDMI"?

 

Then restart the Emby App and try again.

Thanks

Thanks. this actually helped me.Bitstream is now working as expected, and i can also enable all the formats to passthrough.

But one more question, since we are already into the topic. i have the same problem on my Xbox Series S. is there any chance we can fix this problem there too? AFAIK the xbox should also be possible to bitstream all audio? sidenote. the listed "MEC-O-3-H" is an HDMI Matrix switch to split my audio and video signal. since my AV can't  all the resolutions my TV can handle. if this may be am complete other problem on XBOX we can mark this thread as closed, and i can deal with it, since it now works on PC

Actually, this isn't really a problem anymore these days, because what the Xbox does is to decode all bitstream formats (incl. Atmos) and sends the decoded bitstreams  for all individual channels uncompressed via HDMI (for Atmos it re-encodes to Atmos if the TV supports it)

This means that you don't miss anything by letting the console do the decoding. It prefers that, because then it can mix-in its own sounds into the audio signal.
(there are some instructions somewhere to force the Xbox into bitstreaming, but the results were mixed, when I last looked into the subject).

On the PC it's mostly the same. The integrated mpv player also decodes the audio format and sends it as uncompressed audio via HDMI (hence the channel layout settings), but it cannot decode Atmos and DTS:X. The latter two are the only reason to use bitstreaming on a PC and there aren't any on the Xbox actually.
