Hello,

I have a Dell Win 10 64bit Laptop with HDMI Output onboard.
The miniDSP Micro is connected via USB, REW recognizes and works.
HDMI to Marantz - does it work? I do not get it run in REW.
I connect the HDMI cable, Win makes the jingle, Marantz is not doing anything, REW does not show me an active connection, cannot select HDMI ?

THX for help

Do windows see the device with the HDMI connection? Is that playback device listed in the windows control panel for audio devices? REW lists only (possibly a subset of) windows devices (unless ASIO is used which your image shows is not the case).

Hi, already found out that there was a driver issue on Windows, corrected.
Now HDMI signal goes through the Marantz to the display.
Then the HDMI interface in Windows was set to stereo, changed to 7.1
but still the Marantz shows stereo and no signal is getting to the speakers out of REW. ?

New day, new info

Atmos Sample runs on the Marantz via all monitors.

That means REW and ASIO does not work correct on the HDMI interface. What can I do?

When I start a signal, the Marantz always shows L/R/SW, not more. As if it is set to stereo with Sub ? Maybe the Sub is activated by Marantz itself.

If you install V5.20.13, do you have the same problem when using the Java driver?

running the wav via WMP, just Stereo is getting to marantz
windows is set to 7.1 in my opinions, maybe there are more settings?

OK, so there's some problem in general, not specific to REW. While playing that WAV file, if you look at Settings->General->Information on the Marantz, what does it show for Audio Information?

Oh OK

If I play via WMP it is Signal: PCM, Sound - Stereo 48kHz 2/0/0
If I play via Film&TV it is Signal: Direct, Sound- Dolby Atmos

It doesn't look like there was audio playing when you took that picture? What does it look like while the WAV file is actively playing?

OK, so it seems there's something about your Windows audio driver configuration, it appears to be forcibly downmixing to stereo.

Look at all of the tabs for that audio output device (Enhancements, Spatial Sound, etc) to make sure you have any special processing disabled. Look to see if your laptop has some audio control panel or app that might be altering the audio processing.

IMO that Atmos test is obscuring the problem. Atmos/DTS/DD are encoded bitstreams, passed as direct/nonPCM to the AVR which decodes the bitstream to individual channels (something like multichannel mp3). But what is required here is a standard multichannel PCM playback.

I like thothsong's layer-by-layer approach - first testing the driver itself. Only after the lowest layer is confirmed to work, can the subsequent layer on top be tested (REW).

Your laptop is old enough (Win 7 originally, by the sticker) that it might not support multichannel LPCM output, and the driver is always downmixing LPCM.

according to Win Forum, PCM does not have a Stereo problem, seams to be the simplest and workfull option
