Your discussion has moved on but I'd like to conclude the offshoot I
started.
I don't know DXD but I think I understand the underlying issue.
DXD "hide" in a WAV file format - WAV is just a convenient format to
hold the DXD datastream which can be used to trick LMS to send the DXD
data stream content to a DAC unchanged.
For that to happen LMS must think the destination player can support the
file format.
WAV files can hold samples in different formats fixed point PCM, IEEE
Float, 8bit a-Law, 8bit mu-Law and extensible.
LMS players only support fixed point PC and so will have difficulty with
any non PCM format. Different sample size and sample rate can be
handled by LMS
You provided a dump of the file headers of two DXD 325kHz DXD files. As
I understand it one plays and the other doesn't. Summary of the header
analysis is as follows
2 ch, 352.8kHz, 32bits/sample, audio format of sample is IEEE Float :
What-A-Wonderful-World_DXD352KHz_2chDXD.wav
2 ch, 352.8kHz, 24bits/sample, audio format of sample is PCM :
a-fool-for-you-carmen-gomes-inc-dxd352khz.wav
There is a "JUNK" chunk which has some data but is different for each
file. This could be DXD related but AFAICT the data in JUNK is not
passed by LMS or squeezelite to DAC so is ignored.
To understand why the file is unplayable you need to determine whether
the data in the unplayable file WAV fmt header is correct and the audio
DXD data is really in 32 bit floating point and needs to be converted or
whether the fmt file header is wrong and just the header needs to be
corrected.
