Hi All,
I know I've asked this before, and I have gone through the previous answer very carefully but this is a different cause...prob...

I use JRiver exclusively for playing back 5.1 content.
It was quite a struggle to get it working ages ago.
windows PC -> HDMI -> Yamaha receiver -> 5.1 speakers

I've been through the settings adozen times, both windows and JRiver MC. It's version 27 because I'm scared of exaclty this sort of thing - it breaks & I cant fix it.

The current symptoms = every file is now apparently a 2 channel source
I know that's not true, I checked each file with foobar2000 and the display tells me how many channels (6) in each file.
But the little cog wheel pop-up says :
Input:  44.1 kHz 2ch from source format MP3                (file is a 6-channel FLAC format)
Changes: Convert from 2 channels to 5.1 channels

I checked my windows speaker settings, defintiely 5.1.
I also went through the Tools -> Options
I think everything is set as it should be.

Anyone help please?
Thanks in advance./

What does Windows tell you that the files are and how they are named?

[salvadordalisdad]

They're FLACS, and WAV files and allsorts, but none of them are MP3.
I eschew MP3 because it appears incapable of multi-channel, only stereo.

I'm not sure this is a windows thing, it's like MC is reading the files wrongly, but I can't find a setting for it, and the display shows there are 6 channels of sound in the tracks. There's a column you can add called "channels" which actually shows the number of channels.
Same applies to foobar2000, if you load the file & look at "properties" it shows ther number & details of the channels.

TLDR: The files are definitely OK, definitely 6 channels.

Thanks

So often when asking like this, (out loud, not inside your own head), then the brain works differently & gives you time to reflect & figure things out...

The "what does windows think the files are" was the big hint.
They are - without question - good files, and they could not possibly have been corrupted & converted to MP3.
That leads to the obv Q "what could possibly do that - to ALL the files?"

The answer was "The LIBRARY server"
I have a machine on the network which runs MC27 & provides a central library service, for the (soon to be multiple) clients like this one.
It is meant to provide the file location of the FLACS etc, and it does this very reliably.

Who knew it could provide the content as well as (or in this case - instead of) a file location ?
So for some reason it was providing the CONTENT of the files - via an MP3 44.1kHz stream.
I didn't even know it could do that.
Well you live & learn, don't you?

There was a glitch in the fileserver name lookup since a pi-hole update elsewhere on the network, which stopped the hostname/ip lookup from working.
Therefore the file locations were no longer accessible & the "Library" server took it upon itself to provide the content - bless!

So TIL the "Library" can do this - transparently & without letting the user know.
The clue was in the "INPUT: 44.1kHz MP3"

Now we all know what to look for don't we?
Maybe I might update to MC31 now...No I'm not that brave.

Solved.
Thanks for listening.

So now the question is - what broke pi-hole? it never ends...

The server is probably set to convert the files.  You can change that.
