MC 26.0.103 (32-bit) FINALLY playing DSD multichannel files properly!

When I change output format to dolby 5.1 I get white noise out of the right front.
I have the Marantz App and it indicates INPUT as 2 channel PCM and output to all my 5.1 speakers.
I think it is the RASPI or maybe wrong mc settings

Thanks for checking!
The RPi4 is sending stereo 44.1 khz audio over the HDMI to the Marantz. So if you're playing multi-channel files, it looks like the MC/RPi4 is not decoding/encoding it properly.
What version of MC are you running? I seem to recall that I had problems with the Dolby Digital setting outputting white noise on an older version of the MC software. Are you at MC 26.0.103 or higher?
I also found that I had to select the "plughw CARD=b1, DEV=0 [ALSA]" driver (it's under the "Audio Device" setting in MC), and then the Surround Sound started working when I selected "Dolby Digital" in the output format.

That's interesting.
I think it should be sending 48k not 44.1k. I'll check with mine.

Version 107 and I'm using "plughw CARD=b1, DEV=0 [ALSA]" driver" also.
I'm going directly from 5 channel SACD ISO files......to get multi-channel. I have a filter for "CHANNELS>4 and I'm playing those......
I had taken all my iso files and extracted the two channel flac and dsd but not muti-channel. I can repeat the process and do the same extraction with a multi channel extraction and see what happens.....in case it is an ISO playing anomaly. I can also try my multi-channel CD's I've ripped.
What is the format of the files you use for 5.1 playback?

Ok, we're all on the same page!
My multi-channel audio files are in DSF (ripped from DSD) and FLAC (ripped from DVD-Audio and Blu-ray Audio discs) formats. These play back in 5.1 DD Surround with all the channels in the correct speakers, and the Marantz will report back as "DD 48kh" and "Format 3/2/.1".

I just tried a DFF ripped from an SACD Multichannel and if I have Output Format turned off it plays but still in 44.1 and 2/0/0 ... if I turn on Output format at Dolby 5.1 I get ugly white noise and static but it is now 48 and 2/0/.0
Doesn't seem to be affected by anything but output format.
Are you using version MC 107 in your Raspberry? I'm curious that you had white noise.....maybe it was a setting somewhere.
